In one or more embodiments, the electronic device 100 may control the hall sensor 130 to identify (detect) a change in the magnetic force that is generated by the plurality of magnet members 150 and is detected by the hall sensor 130 as the first housing 110 rotates relative to the second housing 120 by a user input.

[0129] In one or more embodiments, when at least one of the plurality of housings rotates, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0130] Referring to FIG. 4A, the second housing 120 may rotate in a first direction (anti-clockwise) relative to the first housing 110. In this case, the magnet member 452 having the second magnetic property may pass through a portion adjacent to the hall sensor 130 first, and then, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 452 having the second magnetic property, first, and then, may detect the magnetic force generated by the magnet member 451 having the first magnetic property.

[0131] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a magnetic force relatively smaller than that of the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the first direction relative to the first housing 110, the magnet member 452 having the second magnetic property which generates a relatively small magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 451 having the first magnetic property which generates a relatively large magnetic force, and then, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, when the second housing 120 rotates in the first direction relative to the first housing 110, the hall sensor 130 may detect the relatively small magnetic force first, and may detect the relatively great magnetic force later.

[0132] Referring FIG. 4B, the second housing 120 may rotate in a second direction (clockwise) which is opposite to the first direction, relative to the first housing 110. In this case, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130, first, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 451 having the first magnetic property, first, and then, may detect the magnetic force generated by the magnet member 452 having the second magnetic property.

[0133] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the magnet member 451 having the first magnetic property that generates a relatively great magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 452 having the second magnetic property that generates a relatively large magnetic force, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4B, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the hall sensor 130 may detect the relatively great magnetic force, first, and may detect the relatively small magnetic force later.

[0134] According to one or more embodiments, the electronic device 100 may identify (detect) an attribute of the plurality of ring-shaped housings rotating relative to each other.

[0135] For example, the attribute of the plurality of ring shaped housings rotating relative to each other may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation. However, embodiments are not limited thereto.

[0136] Referring to FIG. 4A, the second housing 120 may rotate in the first direction relative to the first housing 110. In this case, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130 first, and then, the magnetic member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the electronic device 100 may first detect the magnetic force generated by the magnetic member 452 having the second magnetic property through the hall sensor 130, and then, may detect the magnetic force generated by the magnet member 451 having the first magnetic property and an attribute of change in the magnetic force. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, based on the characteristic of the magnet member 451 having the first magnetic property, the characteristics of the magnet member 452 having the second magnetic property, and the magnetic force detected through the hall sensor 130 and the attribute of change in the magnetic force.

[0137] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the first direction relative to the first housing 110, the magnet member 452 having the second magnetic property that generates a relatively small magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 451 having the first magnetic property that generates a relatively great magnetic force, and thereafter, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4A, when the second housing 120 rotates in the first direction relative to the first housing 110, the hall sensor 130 may first detect the relatively small magnetic force, and may detect the relatively large magnetic force later. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, based on the relatively small magnetic force being detected first by the hall sensor 130 and the relatively great magnetic force being detected later.

[0138] Referring to FIG. 4B, the second housing 120 may rotate in the second direction opposite to the first direction relative to the first housing 110. In this case, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130 first, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 451 having the first magnetic property first, and then, may detect the magnetic force generated by the magnet member 452 having the second magnetic property. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing is the second direction, based on the characteristic of the magnet member 451 having the first magnetic property, the characteristic of the magnet member 452 having the second magnetic property, and the magnetic force detected through the hall sensor 130 or the attribute of change in the magnetic force.

[0139] For example, at a position closest to the hall sensor 130, the magnet members 452, 454, 456, 458 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 451, 453, 455, 457 having the first magnetic property. In this case, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the magnet member 451 having the first magnetic property that generates a relatively great magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 452 having the second magnetic property that generates a relatively large magnetic force, and thereafter, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4B, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the hall sensor 130 may first detect the relatively great magnetic force, and may detect the relatively small magnet force later. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the second direction, based on the relatively great magnetic force being detected first by the hall sensor 130 and the relatively small magnetic force being detected later.

[0140] FIGS. 5A and 5B illustrate a method by which magnet members 150 are arranged in the electronic device 100, and a method of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0141] FIG. 5A illustrates an inner structure of the electronic device 100 which is rotatable in a positive direction 510 or a negative direction 520 on the x-axis. In FIG. 5A, the hall sensor 130 may be disposed in the z-axis direction or on a portion adjacent to the z-axis direction relative to the magnet members 150 with reference to a state in which the plurality of magnet members 150 are disposed closest thereto. For example, the plurality of magnet members 150 may be disposed in the second housing 120, and the hall sensor 130 may be disposed at a position adjacent to the plurality of magnet members 150 in the z-axis direction in the first housing 110.

[0142] FIG. 5B illustrates a graph showing a change attribute in the magnetic force when the second housing 120 of the electronic device 100 rotates in the positive direction 510 on the x-axis relative to the first housing 110, and a graph showing a change attribute in the magnetic force when the second housing 120 of the electronic device 100 rotates in the negative direction 520 of the x-axis relative to the first housing 110.

[0143] Referring to FIG. 5A, the plurality of magnet members 150 may include a plurality of magnet members 150 having different magnitudes of magnetic properties. The plurality of magnet members 150 may include a magnetic member set which is comprised of a plurality of magnet members 150. For example, the magnet member set may include a plurality of magnet members 150 which have different magnitudes of magnetic properties. For example, a plurality of magnet members 150 included in the same magnet member set may be disposed to be in contact with one another, or may be disposed to be spaced apart from one another. For example, the plurality of magnet members 150 included in the same magnet member set may be arranged in the second housing 120 in a direction parallel to the direction in which the second housing 120 rotates relative to the first housing 110. For example, the plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 having different magnitudes of magnetic properties. The two magnet members 150 having different magnitudes of magnetic properties may be disposed such that portions having the same polarity in the magnet members are positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. For example, the two magnet members 150 having different magnitudes of magnetic properties may be disposed such that the portions having the N-pole in the magnet members are positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130.

[0144] For example, referring to FIG. 5, the attribute of the magnetic force detected by the hall sensor 130 may be different according to the direction of rotation of the second housing 120 relative to the first housing 110. The plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 having different magnitudes of magnetic properties. In this case, the two magnet members 150 having different magnitudes of magnetic properties may be disposed such that the portion having the N-pole on each magnet member is positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. In addition, the magnet member that has a relatively large magnitude of a magnetic property out of the two magnet members 150 of the different magnitudes of the magnetic properties may be disposed to be positioned in the positive direction on the x-axis with reference to the magnet member that has a relatively small magnitude of a magnetic property.

[0145] For example, when the second housing 120 rotates relative to the first housing 110, some of the magnet members 150 may rotate toward the positive direction 510 on the x-axis in the portion closest to the hall sensor 130. In this case, the magnet member that has the relatively large magnitude of the magnetic property may reach the position adjacent to the hall sensor before the magnet member that has the relatively small magnitude of the magnetic property. In this case, as shown in FIG. 5B, the hall sensor 130 may first detect the relatively strong magnetic force, and may detect the relatively weak magnetic force later. The electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on the relatively strong magnetic force being detected before the relatively weak magnetic force.

[0146] For example, when the second housing 120 rotates with reference to the first housing 110, some of the magnet members 150 may rotate toward the negative direction 520 on the x-axis in the portion closest to the hall sensor 130. In this case, the magnet member that has the relatively small magnitude of the magnetic property may reach the position adjacent to the hall sensor 130 before the magnet member that has the relatively large magnitude of the magnetic property. Accordingly, as shown in FIG. 5B, the hall sensor 130 may first detect the relatively weak magnetic force, and may detect the relatively strong magnetic force later. The electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on the relatively weak magnetic force being detected through the hall sensor 130 before the relatively strong magnetic force.

[0147] FIGS. 6A and 6B are views to explain an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0148] FIG. 6A may correspond to FIG. 5A, and FIG. 6B may correspond to FIG. 5B. Accordingly, redundant explanations may be omitted and the difference between the embodiment shown in FIGS. 5A and 5B and the embodiment shown in FIGS. 6A and 6B will be highlighted.

[0149] Compared to the embodiment illustrated in FIGS. 5A and 5B, the embodiment of FIGS. 6A and 6B has magnet members 150 which are included in a single magnet member set and are positioned at a relatively long distance.

[0150] In one or more embodiments, the plurality of magnet members 150 included in the single magnet member set may be disposed adjacent to one another or may be disposed at relatively long distances. As shown in FIG. 6A, the plurality of magnet members 150 may be arranged at relatively longer intervals than in the embodiment illustrated in FIG. 5A. In this case, a time period during which a relatively strong magnetic force is detected and a time period during which a relatively weak magnetic force is detected may be relatively clearly distinguished from each other. In this case, referring to the graphs of the change in the magnetic force shown in FIG. 5B and FIG. 6B, in the graph of the change in the magnetic force shown in FIG. 6B, the period during which a relatively strong magnetic force is detected and the period during which a relatively weak magnetic force is detected may be identified more clearly. Accordingly, compared to when the plurality of magnet members 150 are completely in contact with one another or are positioned at relatively short distances, when the plurality of magnet members 150 are positioned at relatively long distances, the change in the magnetic force may be more clearly identified, so that malfunction may be minimized and the accuracy of identifying the rotation attribute of the housing may be enhanced. Accordingly, the gaps between the plurality of magnet members may be set to a predetermined distance or longer in order to enhance the accuracy of identifying the rotation attribute of the housing and to reduce the probability of malfunction.

[0151] FIGS. 7A, 7B, and 7C are views to explain an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0152] Referring to FIG. 7A, the plurality of magnet members 150 may include a plurality of magnet members 150 having different polarities. In one or more embodiments, the plurality of magnet members 150 may be disposed in the second housing 12 such that portions of different polarities in the respective magnet members are adjacent to the first housing 110. For example, the plurality of magnet members 150 may include a first magnet member and a second magnet member, and may be disposed in the second housing 120, such that a portion of the first magnet member that has a first polarity and a portion of the second magnet member that has a second polarity are adjacent to the first housing 110. In this case, the portion of the first magnet member having the first polarity and the portion of the second magnet member having the second polarity may be disposed in a direction adjacent to the hall sensor 130 in the first housing 110. For example, the first polarity and the second polarity may be opposite polarities. For example, the plurality of magnet members 150 may include a first magnet member and a second magnet member, and may be disposed in the second housing 120 such that the N-pole portion of the first magnet member and the S-pole portion of the second magnet member are adjacent to the first housing 110.

[0153] Referring to FIG. 7C, the N-pole portion and the S-pole portion of one magnet member may be disposed in the second housing 120 to be adjacent to the first housing 110. In one or more embodiments, as shown in FIG. 7C, portions of the different polarities in one magnet member may be arranged on the second housing 120 along a direction in which the second housing 120 rotates relative to the first housing 110. The plurality of magnet members 150 may include a magnet member set which is comprised of a plurality of magnet members 150. For example, the magnet member set may include a plurality of magnet members 150 with different polarities. For example, the plurality of magnet members 150 included in the same magnet member set may be disposed to be in contact with one another, or may be disposed to be spaced apart from one another. For example, the plurality of magnet members 150 included in the same magnet member set may be arranged such that portions having different polarities are disposed on the second housing 120 along the direction in which the second housing 120 rotates relative to the first housing 110. For example, two magnet members 150 may be disposed such that the portions having different polarities in the respective magnet members are positioned in the direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130.

[0154] Referring to the examples of FIGS. 7A, 7B, and 7C, the attribute of the magnetic force detected by the hall sensor 130 may vary according to the direction in which the second housing 120 rotates relative to the first housing 110. In one or more embodiments, the plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 with different polarities. The two magnet members 150 with different polarities may be disposed such that the N-pole portion and the S-pole portion of the magnet members are positioned in the direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. The magnet member having the N-pole portion that is disposed in the direction adjacent to the hall sensor 130 out of the two magnet members 150 with different polarities may be disposed to be positioned in the positive direction on the x-axis with reference to the magnet member having the S-pole portion that is disposed in the direction adjacent to the hall sensor 130.

[0155] Referring to FIGS. 7A and 7C, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the positive direction 710 on the x-axis in the portion closest to the hall sensor 130. In this case, the S-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the N-pole portion. Accordingly, referring to FIG. 7B, when the S-pole portion of a magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120 (for example, the negative direction on the z-axis in FIGS. 7A and 7C), the hall sensor 130 may detect the repulsive force first and may detect the attractive force later. The electronic device may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the repulsive force being detected before the attractive force through the hall sensor 130.

[0156] Referring to FIGS. 7A and 7B, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the negative direction 702 on the x-axis in the portion closest to the hall sensor 130. In this case, the N-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the S-pole portion of the magnet member. Accordingly, referring to FIG. 7B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120, the hall sensor 130 may detect the attractive force first and may detect the repulsive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the attractive force being detected before the repulsive force through the hall sensor 130.

[0157] FIGS. 8A and 8B illustrate an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0158] In the embodiments of FIGS. 4A to 7C, the hall sensor 130 and the plurality of magnet members 150 are disposed in different housings. However, according to one or more embodiments, an arrangement direction of a magnet member in the hall sensor 130 may be changed as shown in FIGS. 8A and 8B.

[0159] Referring to FIG. 8A, the N-pole portion and the S-pole portion of the magnet member in the hall sensor 130 may be disposed along the direction in which the first housing 110 rotates relative to the second housing 120. In one or more embodiments, as shown in FIG. 8A, the portions of different polarities in one magnet member may be disposed in the hall sensor 130 along the direction in which the first housing 110 rotates relative to the second housing 120 (for example, in the +x-axis direction or-x-axis direction of FIG. 8A).

[0160] Referring to the example of FIGS. 8A and 8B, the attribute of the magnetic force detected by the hall sensor 130 may be different according to the direction in which the second housing 120 rotates relative to the first housing 110.

[0161] For example, referring to FIG. 8A, when the second housing 120 rotates relative to the first housing 110, some magnet members may rotate toward the positive direction 810 on the x-axis in the portion closest to the hall sensor 130. In this case, the S-pole portion of the magnet member in the hall sensor 130 may reach the position adjacent to the hall sensor 130 before the N-pole portion. Accordingly, referring FIG. 8B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in a direction adjacent to the second housing 120 (for example, the negative direction on the z-axis in FIG. 8A), the hall sensor 130 may detect the attractive force first, and may detect the repulsive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the repulsive force being detected before the attractive force through the hall sensor 130.

[0162] Referring to FIG. 8A, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the negative direction 820 on the x-axis in the portion closest to the hall sensor 130. In this case, the N-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the S-pole portion. Accordingly, referring to FIG. 8B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120, the hall sensor 130 may detect the repulsive force first and may detect the attractive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the attractive force being detected before the repulsive force through the hall sensor 130.

[0163] FIGS. 9A and 9B illustrate example of arrangements of magnet members 150 at different intervals in the electronic device, and a change attribute in in the magnetic force according to one or more embodiments.

[0164] FIG. 9A illustrates an example of arrangements of magnet members 150 at different intervals in the electronic device 100 according to one or more embodiments, and FIG. 9B is a graph showing a change attribute in the magnetic force while the second housing 120 is rotating relative to the first housing 110 when the magnet members 150 are arranged at different intervals as shown in FIG. 9A.

[0165] According to one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals.

[0166] In one or more embodiments, at least a part of the plurality of magnet members 150 may be a plurality of magnet members 150 which are arranged at different intervals. In one or more embodiments, the gaps between the plurality of magnet members 150 may all be different. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually increase. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually decrease. For example, when N magnet members 150 are arranged in the electronic device 100, the plurality of magnet members 150 may include a first magnet member, a second magnet member, . . . , an M-th magnet member, . . . , and an N-th magnet member. For example, the gap between the second magnet member and the third magnet member may be larger than the gap between the first magnet member and the second magnet member, and the gap between the M-th magnet member and the M+1-th magnet member may be larger than the gap between the M−1-th magnet member and the M-th magnet member. For example, the gap between the first magnet member and the second magnet member may have the smallest value, and the gap between the N−1-th magnet member and the N-th magnet member may have the largest value.

[0167] Referring to FIG. 9A, a plurality of magnet members (for example, 150 of FIG. 1, 910, 912, 914, 916, 918, 920 of FIG. 9A) may be arranged such that the gaps between the plurality of magnet members (for example, 150 of FIG. 1, 910, 912, 914, 916, 918, 920 of FIG. 9A) gradually increase. Referring to FIG. 9A, six magnet members 910, 912, 914, 916, 918, 920 may be arranged in the electronic device 100. The six magnet members 150 may be the first magnet member 910, the second magnet member 912, the third magnet member 914, the fourth magnet member 916, the fifth magnet member 918, and the sixth magnet member 920. For example, a gap between the first magnet member 910 and the second magnet member 912 may be a first gap, a gap between the second magnet member 912 and the third magnet member 914 may be a second gap, a gap between the third magnet member 914 and the fourth magnet member 916 may be a third gap, a gap between the fourth magnet member 916 and the fifth magnet member 918 may be a fourth gap, and a gap between the fifth magnet member 918 and the sixth magnet member 920 may be a fifth gap. In this case, for example, the second gap may have a larger value than the first gap, the third gap may have a larger value than the second gap, the fourth gap may have a larger value than the third gap, and the fifth gap may have a larger value than the fourth gap. In this case, referring to FIGS. 9A and 9B, when the second housing 120 rotates relative to the first housing 110, the plurality of magnet members 150 may rotate in a direction to cause the first magnet member 910, the second magnet member 912, the third magnet member 914, and the fourth magnet member 916 to reach the position closest to the hall sensor 130 in sequence. In this case, the time interval between the times at which the greatest magnetic force is detected may gradually increase. For example, the time interval between the time 922 at which the greatest magnetic force is detected by the second magnet member 912 at the hall sensor 130 and the time 924 at which the greatest magnetic force is detected by the third magnet member 914 at the hall sensor 130 may be longer than the time interval between the time 920 at which the greatest magnetic force is detected by the first magnet member 910 at the hall sensor 130 and the time 922 at which the greatest magnetic force is detected by the second magnet member 912 at the hall sensor 130. In one or more embodiments, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual increase in the time interval between the times 920, 922, 924 at which the greatest magnetic force is detected through the hall sensor 130.

[0168] In one or more embodiments, when the second housing 120 rotates relative to the first housing 110 in a direction opposite to the embodiment described above, the electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual decrease in the time interval between the times 920, 922, 924 at which the greatest magnetic force is detected through the hall sensor 130.

[0169] In one or more embodiments, the plurality of magnet members 150 may be irregularly arranged at different intervals without a gradual increase or decrease in the gaps between the plurality of magnet members 150. In this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the gaps between the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0170] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals and have different magnetic properties. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the magnetic properties of the plurality of magnet members 15, information on the gaps between the plurality of magnet members 150, and a change attribute in the magnetic force detected through the hall sensor 130.

[0171] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet member sets each including a plurality of magnet members 150. In one or more embodiments, at least some of the plurality of magnet member sets may be a plurality of magnet member sets which are arranged at different intervals. In one or more embodiments, the gaps between the plurality of magnet member sets may all be different. In one or more embodiments, the plurality of magnet member sets may be arranged such that the gaps between the plurality of magnet member sets gradually increase. In one or more embodiments, the plurality of magnet member sets may be arranged such that the gaps between the plurality of magnet member sets gradually decrease.

[0172] FIGS. 10A and 10B illustrate examples of arrangement of magnet members 150 having different magnetic properties in the electronic device, and a change attribute in the magnetic force according to one or more embodiments.

[0173] According to one or more embodiments, at least one magnet member of the plurality of magnet members 150 may have a different magnetic property from that of at least one other magnet member. In one or more embodiments, the magnet members 150 having different magnetic properties may include the magnet members 150 having different magnetic forces acting on the hall sensor 130. For example, the magnet members having different magnetic properties may include the magnet members 150 having different polarities of magnetic forces acting on the hall sensor 130. For example, the magnet members having different magnetic properties may include the magnet members 150 having different magnitudes of magnetic forces acting on the hall sensor 130.

[0174] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged in order of decreasing the magnitude of the magnetic property. In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged in order of increasing the magnitude of the magnetic property. For example, the plurality of magnet members 150 may further include a first magnet member, a second magnet member, and a third magnet member, and the first magnet member, the second magnet member, and the third magnet member may be arranged in order of decreasing the magnitude of the magnetic property.

[0175] FIG. 10A illustrates an example of the plurality of magnet members 150 which are arranged in the electronic device 100 in order of decreasing the magnitude of the magnetic property, and FIG. 10B is a graph showing a change attribute in the magnetic force while the second housing 120 is rotating relative to the first housing 110 when the magnet members 150 are arranged in order of decreasing the magnitude of the magnetic property as shown in FIG. 10A.

[0176] In one or more embodiments, at least some of the plurality of magnet members 150 may be a plurality of magnet members 150 which have magnetic properties of different magnitudes. In one or more embodiments, the magnitudes of the magnetic properties of the plurality of magnet members 150 may all be different. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the magnitude of the magnetic property of each magnet member gradually increases. In one or more embodiments, the plurality of magnet members 150 may be arranged in order of decreasing the magnitude of the magnetic property. For example, when N magnet members 150 are arranged in the electronic device 100, the plurality of magnet members 150 may include a first magnet member, a second magnet member, . . . , an M-th magnet member, . . . , and an N-th magnet member. For example, the magnitude of the magnetic property of the second magnet member may be greater than the magnitude of the magnetic property of the first magnet member, and the magnitude of the magnetic property of the M-th magnet member may be greater than the magnitude of the magnetic property of the M−1-th magnet member. For example, the magnitude of the magnetic property of the first magnet member may have a smallest value out of the N magnet members 150, and the magnitude of the magnetic property of the N-th magnet member may have a greatest value.

[0177] Referring to FIG. 10A, a plurality of magnet members (for example, 150 of FIG. 1, 1010, 1012, 1014, 1016, 1018, 1020, 1022, 1024 of FIG. 10A) may be arranged in order of decreasing the magnitude of the magnetic property. Referring to FIG. 10A, 8 magnet members (for example, 150 of FIG. 1, 1010, 1012, 1014, 1016, 1018, 1020, 1022, 1024 of FIG. 10A) may be disposed in the electronic device 100, and the 8 magnet members 150 may be a first magnet member 1010, a second magnet member 1012, a third magnet member 1014, a fourth magnet member 1016, a fifth magnet member 1018, a sixth magnet member 1020, a seventh magnet member 1022, and an eighth magnet member 1024. In this case, the magnitude of the magnetic property of the second magnet member may have a greater value than the magnitude of the magnetic property of the first magnet member, the magnitude of the magnetic property of the third magnet member may have a greater value than the magnitude of the magnetic property of the second magnet member, and the magnitude of the magnetic property of the fourth magnet member may have a greater value than the magnitude of the magnetic property of the third magnet member. In this case, referring to FIGS. 10A and 10B, when the second housing 120 rotates relative to the first housing 110, the plurality of magnet members 150 may rotate in such a direction that the first magnet member 1010, the second magnet member 1012, the third magnet member 1014, and the fourth magnet member 1016 reach the position closest to the hall sensor 130 in sequence. In this case, the maximum value 1030, 1032, 1034 of the magnetic force detected may gradually decrease with time. For example, the maximum value of the magnetic force detected at the time 1032 at which the greatest magnetic force is detected by the second magnet member 1012 at the hall sensor 130 may be greater than the maximum value of the magnetic force detected at the time 1030 at which the greatest magnetic force is detected by the first magnet member 1010 at the hall sensor 130. In one or more embodiments, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual increase in the time interval between the times 1030, 1032, 1034 at which the greatest magnetic force is detected through the hall sensor 130.

[0178] In one or more embodiments, when the second housing 120 rotates relative to the first housing 110 in a direction opposite to the embodiment described above, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual decrease in the maximum value of the magnetic force at the time when the greatest magnetic force is detected through the hall sensor 130.

[0179] In one or more embodiments, the plurality of magnet members 150 may be irregularly arranged regardless of the magnitude of the magnetic property without a gradual increase or decrease in the magnitude of the magnetic property of the plurality of magnet members 150. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 to the first housing 110, based on information on the magnetic property of the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0180] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals and have different magnetic properties. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the magnetic property of the plurality of magnetic members 150, information on the gaps between the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0181] FIGS. 11A and 11B illustrate a change attribute in the magnetic force according to a rotation speed of a housing in the electronic device according to one or more embodiments.

[0182] FIGS. 11A and 11B are views for comparing the periods of change in the magnetic force when the speed at which the second housing 120 rotates relative to the first housing 110 is different in the electronic device 100 of the same configuration. For example, FIG. 11A illustrates a case where the second housing 120 rotates relative to the first housing 110 at a relatively fast speed, and FIG. 11B illustrates a case where the second housing 120 rotates relative to the first housing 110 at a relatively slow speed.

[0183] According to one or more embodiments, in the electronic device 100 of the same configuration, when the second housing 120 rotates relative to the first housing 110 at a relatively fast speed (FIG. 11A), the period in which the plurality of magnet members 150 reach the position closest to the hall sensor 130 may be shorter than when the second housing 120 rotates relative to the first housing 110 at a relatively slow speed (FIG. 11B). Accordingly, when the second housing 120 rotates relative to the first housing 110 at the relatively fast speed (FIG. 11A), the period in which the magnetic force sensed by the hall sensor 130 has a maximum value may be shorter than when the second housing 120 rotates relative to the first housing 110 at the relatively slow speed (FIG. 11B). For example, when the second housing 120 rotates relative to the first housing 110 at the relatively fast speed (FIG. 11A), the period of change in the magnetic force sensed by the hall sensor 130 may be shorter than when the second housing 120 rotates relative to the first housing 110 at the relatively slow speed (FIG. 11B).

[0184] According to one or more embodiments, the electronic device 100 may identify (detect) a speed at which the second housing 120 rotates relative to the first housing 110, based on the period of change in magnetic force detected by the hall sensor 130. For example, the electronic device 100 may identify (detect) that the speed at which the second housing 120 rotates relative to the first housing 110 is relatively high when the period of change in the magnetic force detected via the hall sensor 130 is relatively short. For example, the electronic device 100 may identify (detect) that the speed at which the second housing 120 rotates relative to the first housing 110 is relatively low when the period of change in the magnetic force detected via the hall sensor 130 is relatively long.

[0185] According to one or more embodiments, the method by which the magnet members 150 are arranged may include a number of different methods, and is not limited to the above-described embodiments.

[0186] FIG. 12 is a flowchart of a process of identifying an attribute of rotation of the second housing 120 relative to the first housing 110 in the electronic device according to one or more embodiments.

[0187] At step 1210, the second housing 120 may rotate relative to the first housing 110.

[0188] According to one or more embodiments, the electronic device 100 may include ring-shaped housings. The electronic device 100 according to one or more embodiments may be worn on a user by the ring-shaped housings. According to one or more embodiments, the electronic device 100 may include a plurality of ring-shaped housings, and may be worn on a user by the plurality of ring-shaped housings. The plurality of ring-shaped housings may be coupled (connected) to be rotatable relative to at least one other housing. At least one of the plurality of ring-shaped housings may be rotated relative to at least one other housing under force from the user. In one or more embodiments, at least one of the plurality of ring-shaped housings may be rotated relative to at least one other housing by receiving a rotating force from the user. For example, while the electronic device 100 is worn by the user, at least a part of the plurality of ring-shaped housings included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force from the user. For example, while the electronic device 100 is worn on user's index finger, at least a part of the plurality of ring-shaped housings included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force by user's thumb.

[0189] At step 1220, the magnetic force generated between the plurality of magnet members 150 and the hall sensor 130 may change. In one or more embodiments, as the second housing 120 rotates relative to the first housing 110, the magnetic force generated between the plurality of magnet members 150 and the hall sensor 130 may change. For example, when the magnet member reaches a portion closest to the hall sensor 130 due to the rotation of the housing, the magnetic force detected by the hall sensor 103 may have a maximum value or a minimum value. For example, as the gap between the magnet member and the hall sensor 130 changes due to the rotation of the housing, the magnetic force detected by the hall sensor 130 may change. For example, as the distance between the magnet member and the hall sensor 130 continuously changes due to the rotation of the housing, the magnetic force detected by the hall sensor 130 may continuously change.

[0190] At step 1230, the electronic device 100 may detect the change in the magnetic force through the hall sensor 130. In one or more embodiments, the hall sensor may detect the existence of a magnetic field, a location of occurrence, and a strength thereof. In one or more embodiments, the hall sensor 130 and the plurality of magnet members 150 may be disposed in different housings. In one or more embodiments, the hall sensor 130 included in the electronic device 100 may detect a change in the magnetic force acting on the hall sensor 130 according to the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings when at least one of the plurality of housings rotates. For example, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings when at least one of the plurality of housings rotates. For example, the electronic device 100 may include a first housing 110 and a second housing 120, and, when the second housing 120 rotates relatives to the first housing 110, the hall sensor 130 included in the first housing 110 may detect a change in the magnetic force acting on the hall sensor 130 and an attribute thereof by the rotation of the plurality of magnet members 150 included in the second housing 120.

[0191] At step 1240, the electronic device 100 may identify (detect) the change attribute in the magnetic force detected. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0192] At step 1250, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110. According to one or more embodiments, the electronic device 100 may identify (detect) the attribute of rotation of the second housing 120 relative to the first housing 110, based on the change attribute in the magnetic force detected. The attribute of the plurality of ring-shaped housings rotating relative to one another may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation. However, embodiments are not limited thereto.

[0193] FIG. 13 illustrates the electronic device 100 and peripheral devices of the electronic device 100 according to one or more embodiments.

[0194] In one or more embodiments, there may exist the electronic device 100, a first external electronic device 1310, a gateway 1320, and at least one second external electronic devices 1333, 1337.

[0195] The electronic device 100 may communicate with the first external electronic device 1310 via an antenna (for example, 280 of FIG. 2). For example, the first external electronic device 1310 may be a smartphone.

[0196] In one or more embodiments, the first external electronic device 1310 may communicate with the gateway 1320. For example, the gateway 1320 and the first external electronic device 1310 may communicate by using Wi-Fi.

[0197] In one or more embodiments, the gateway 1320 may communicate with at least one second external electronic device 1333, 1337. The second external electronic device 1333, 1337 may be, for example, a home appliance (for example, an air conditioner, a television (TV), a refrigerator). For example, the gateway 1320 may transmit a signal to control the second external electronic device 1333, 1337 to the second external electronic device 1333, 1337.

[0198] FIG. 14 is a flowchart illustrating a process of the second external electronic device performing an operation corresponding to an identified rotation attribute according to the identified rotation attribute of the electronic device in the electronic device according to one or more embodiments.

[0199] At step 1410, the electronic device 100 may transmit a signal corresponding to an identified rotation attribute to the first external electronic device 1310. In one or more embodiments, the electronic device 100 may transmit six-axis information to the first external electronic device 1310 through Bluetooth communication. For example, the attribute of the plurality of ring-shaped housings rotating relative to one another may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation.

[0200] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device 1333, 1337 may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher.

[0201] For example, the identified rotation attribute may include information indicating that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, and the second external electronic device 1333, 1337 may be a device that performs a temperature control function. In this case, the electronic device 100 may transmit a signal to increase a target temperature of the second external electronic device 1333, 1337 to the first external electronic device 1310. For example, the identified rotation attribute may include information indicating that the rotation direction is the second direction opposite to the first direction, and the second external electronic device 1333, 1337 may be a device that performs a temperature control function. In this case, the electronic device 100 may transmit a signal to reduce the target temperature of the second external electronic device 1333, 1337 to the first external electronic device.

[0202] At step 1420, the first external electronic device 1310 may discover the second external electronic device 1333, 1337. According to one or more embodiments, the first external electronic device 1310 may receive six-axis information from the electronic device 100, and may transmit a signal related to the received information to the second external electronic device 1333, 1337. According to one or more embodiments, the first external electronic device 1310 may discover the second external electronic device 1333, 1337 existing in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and position information received from the second external electronic device 1333, 1337. In one or more embodiments, the second external electronic device 1333, 1337, which is intended to receive a signal from the first external electronic device 1310, may be discovered through antennas of the electronic device 100 and the second external electronic device 1333, 1337. The process of discovering the second external electronic device 1333, 1337 by the first external electronic device 1310 will be described in detail with reference to FIGS. 15 to 19.

[0203] At step 1430, the first external electronic device 1310 may transmit a signal to perform an operation corresponding to the identified rotation attribute to the second external electronic device 1333, 1337.

[0204] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher. The first external electronic device which receives the signal may discover the second external electronic device 1333, 1337 which exists in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and location information received from the second external electronic device 1333, 1337. The first external electronic device 1310 may transmit the signal that causes the second external electronic device 1333, 1337 identified by discovering to increase the reproduction speed of the content by a predetermined value or higher to the second external electronic device 1333, 1337.

[0205] At step 1440, the second external electronic device 1333, 1337 may perform the operation corresponding to the identified rotation attribute.

[0206] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher. The first external electronic device which receives the signal may discover the second external electronic device 1333, 1337 which exists in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and location information received from the second external electronic device 1333, 1337. The first external electronic device 1310 may transmit the signal that causes the second external electronic device 1333, 1337 identified by discovering to increase the reproduction speed of the content by a predetermined value or higher to the second external electronic device 1333, 1337. The second external electronic device 1333, 1337 which receives the signal may control an audio to increase the reproduction speed of the reproduced content by a predetermined value or higher.

[0207] FIG. 15 is a flowchart of a process of communicating with the second external electronic device through the first external electronic device by the electronic device according to one or more embodiments.

[0208] The second external electronic device 1330 of FIG. 15 may correspond to the second external electronic device 1333, 1337 of FIGS. 13, 17, and 18.

[0209] According to one or more embodiments, when the electronic device 100 detects that the electronic device is disconnected from a charger after being connected to the charger (1501), the electronic device may execute a mode for communicating with external electronic devices. For example, the electronic device 100 may execute a BLE connection mode (1502). When the electronic device 100 identifies the first external electronic device 1310, a Bluetooth Low Energy (BLE) connection may be performed between the first external electronic device 1310 and the electronic device 100 (1509). For example, the electronic device 100 and the first external electronic device 1310 may be already paired with each other or may be initially connected with each other.

[0210] According to one or more embodiments, the electronic device 100 may detect that the electronic device 100 is worn on user's body through a sensor module (1503). For example, the electronic device 100 may acquire biometric recognition information of the user through the sensor module (1504). For example, the recognized biometric recognition information may be used for identifying the user (1505). For example, the electronic device 100 may store a setting value related to at least one user in a memory (for example, a memory 220 of FIG. 2). In this case, the electronic device 100 may identify (detect) the user by comparing the recognized biometric recognition information and the stored setting value (1505). For example, the electronic device 100 may determine whether to give an authority to control the second external electronic device 1330 to the identified user according to the identified user. For example, the electronic device 100 may determine the second external electronic device 1330 to control according to the identified user. For example, when the identified user is a first user and a setting value corresponding to the first user is related to TV control, the electronic device 100 may determine the second external electronic device 1333, 1337 to identify (detect) as a television (TV).

[0211] In one or more embodiments, the electronic device 100 may transmit six-axis information of the electronic device 100 which is acquired through the sensor module to the first external electronic device 1310 (1506). A six-axis sensor may include a gyro sensor or an acceleration sensor, and may acquire the 6-axis information. The first external electronic device 1310 which receives the six-axis information from the electronic device 100 (1511) may transmit the six-axis information to the second external electronic device 1330 through the gateway 1320 (1513). The second external electronic device 1330 may receive the six-axis information of the electronic device 100 (1516), and may identify (detect) whether the second external electronic device 1330 is positioned in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the received 6-axis information of the electronic device 100 and the location information of the second external electronic device (1517). For example, the second external electronic device 1330 may identify (detect) whether the second external electronic device 1330 is positioned in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the relative positions among the first external electronic device 1310, the second external electronic device 1330 and the electronic device 100, and the 6-axis information of the electronic device 100 (1517).

[0212] In one or more embodiments, when it is identified that the second external electronic device 1330 is positioned in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, the second external electronic device 1330 may execute a mode to be controlled by the electronic device 100 (1518), and the electronic device 100 may execute a mode for controlling the second external electronic device 1330 (1507). When it is detected that the second housing 120 of the electronic device 100 rotates relative to the first housing 110 in the state in which the mode is executed in each of the electronic device 100 and the second external electronic device 1330 (1508), a related signal may be transmitted to the second external electronic device 1330 through the first external electronic device 1310 and the gateway 1320. The second external electronic device 1330 which receives the signal may perform an operation corresponding to the attribute of rotation of the second housing 120 of the electronic device 100 relative to the first housing 110 (1519).

[0213] FIGS. 16A, 16B, and 16C are views to explain a method by which the electronic device identifies positions of external electronic devices through an antenna 280 according to one or more embodiments.

[0214] FIG. 16A illustrates one or more embodiments in which an antenna 280 is disposed in the electronic device 100. In one or more embodiments, the antenna 280 may be disposed in the housing 110, 120 of the electronic device 100. In one or more embodiments, the antenna 280 may be a part of the housings 110, 120 of the electronic device 100. For example, the antenna 280 may be at least a part of the metal segment portion of the first housing 110 or the second housing 120. For example, the antenna 280 may include a monopole antenna or a dipole antenna.

[0215] FIG. 16B illustrates a method by which the antenna 280 is disposed in the first external electronic device 1310, the second external electronic device 1330, 1333, 1337, and the gateway 1320. In one or more embodiments, the antenna 280 may be an antenna array in which a plurality of antennas are connected. For example, the antenna 280 may be an antenna array that is arranged in the horizontal or vertical direction. Referring to FIG. 16B, a first patch antenna, a second patch antenna, and a third patch antenna may be disposed and operate in one device.

[0216] FIG. 16C illustrates a method of identifying a position of the first external electronic device 1310 or the second external electronic device 1330, 1333, 1337 through the antenna 280. For example, the antenna 280 may be an antenna that operates in an angle of departure (AoD) method or an angle of arrival (AoA) method. For example, the plurality of antennas included in the antenna array may determine a phase difference of signals by the following Equation 1:Phase⁢ Difference=d⁢ sin⁢ θ×2⁢πλEquation⁢ 1

[0217] For example, the plurality of antennas may identify (detect) relative positions of the electronic device 100 and the second external electronic device 1333, 1337, based on the phase difference between signals, which is determined by Equation 1 above.

[0218] FIG. 17 illustrates a connection structure between the electronic device and external electronic devices, and a position identification method according to one or more embodiments.

[0219] In one or more embodiments, there may exist an electronic device 100, a first external electronic device 1310, a gateway 1320, and at least one second external electronic device 1333, 1337. According to one or more embodiments, the electronic device 100 may include a BLE module (for example, a communication module 230 of FIG. 2) for Bluetooth communication, a six-axis sensor (for example, a gyro sensor, an acceleration sensor), an antenna (for example, an antenna 280 of FIG. 2), or a processor (for example, a processor 210 of FIG. 2).

[0220] The first external electronic device 1310 may include a processor and may include a communication module for Wi-Fi and Bluetooth communication.

[0221] The second external electronic device 1333, 1337 may include a processor, and may include a plurality of antenna arrays for performing BLE communication.

[0222] In one or more embodiments, a BLE connection may be performed between the first externa electronic device 1310 and the electronic device 100 (1509). For example, the electronic device 100 and the first external electronic device 1310 may be already paired with each other, or may be initially connected with each other.

[0223] In one or more embodiments, the electronic device 100 may transmit six-axis information of the electronic device 100 acquired through a sensor module to the first external electronic device 1310. The six-axis sensor may include a gyro sensor or an acceleration sensor and may acquire six-axis information. The first external electronic device 1310 which receives the six-axis information from the electronic device 100 may transmit the six-axis information to the second external electronic device 1333, 1337 through the gateway 1320.

[0224] For example, the antennas of the second external electronic device 1333, 1337 and the electronic device 100 may operate in the AoD method to cause the second external electronic device 1333, 1337 to acquire the six-axis information of the electronic device 100.

[0225] The second external electronic device 1333, 1337 may receive the six-axis information of the electronic device 100, and may identify (detect) whether the second external electronic device 1333, 1337 is positioned in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information of the electronic device 100 received, and position information of the second external electronic device 1333, 1337.

[0226] FIG. 18 illustrates a method of identifying positions of the electronic device and external electronic devices according to one or more embodiments.

[0227] According to one or more embodiments, the electronic device 100, the first external electronic device 1310 or the second external electronic device 1333, 1337 may include an antenna array that performs short-range wireless communication. For example, the electronic device 100, the first external electronic device 1310, or the second external electronic device 1333, 1337 may perform wireless communication by using ultra-wide band (UWB) wireless communication. In this case, each of the devices may use a wide frequency domain within a low-frequency domain, so that each of the devices may perform wireless communication without mutual interference with an existing communication system even with low spectrum power.

[0228] In one or more embodiments, the relative positions of the electronic device 100 and the second external electronic device 1333, 1337 may be identified by using the antennas of the electronic device 100 and the second external electronic device 1333, 1337.

[0229] In one or more embodiments, there may be a plurality of second external electronic devices 1333, 1337. In this case, the relative positions of the electronic device 100 and the second external electronic devices 1333, 1337 may be identified by using trilateration between the first external electronic device 1310 and the plurality of second external electronic devices 1333, 1337 or the plurality of second external electronic devices 1333, 1337.

[0230] FIGS. 19A and 19B illustrate a range in which the electronic device identifies whether an external electronic device is positioned in a direction that a rotation surface of a housing faces according to one or more embodiments.

[0231] FIGS. 19A and 19B are views to explain a method of setting a reference range for identifying whether the second electronic device 1333, 1337 is positioned in a direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces when a distance between the electronic device 100 and the second external electronic device 1333, 1337 is relatively long and when the distance is relatively short.

[0232] According to one or more embodiments, the second external electronic device 1333, 1337 being positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may include the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces facing at least a part of the outer side of the second electronic device 1333, 1337.

[0233] Referring to FIGS. 19A and 19B, the electronic device 100 may be positioned at different positions (for example, position 1, position 2), and the electronic device 100 may form an azimuth of the same degree (90°-θ) with reference to the second external electronic device 1333, 1337. Even if the electronic device 100 is positioned at a position forming the azimuth of the same degree with reference to the second external electronic device 1333, 1337, when the distance (for example, d1, d2) between the electronic device 100 and the second external electronic device 1333, 1337 is different, the angle range (for example, α1, β1) in which it is identified that the second external electronic device 1333, 1337 is positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may be different. For example, when the distance d2 between the electronic device 100 and the second external electronic device 1333, 1337 is relatively long (for example, when the electronic device 100 is positioned at position 2), the angle range (β1) in which it is identified that the second external electronic device 1333, 1337 is positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may be narrower than when the distance (d1) between the electronic device 100 and the second external electronic device 1333, 1337 is relatively short (for example, when the electronic device 100 is positioned at position 1) (β1<α1).

[0234] FIG. 20 illustrates an example of controlling an external electronic device that is positioned in a direction that a rotation surface of a housing of the electronic device faces according to one or more embodiments.

[0235] Referring to FIG. 20, the electronic device 100 may change the second external electronic device 1333, 1337 to be controlled, or may not control the second external electronic device 1333, 1337 according to a position of the second housing 120 relative to the hall sensor 130 that is displaced in response to the rotation of the second housing 120 relative to the first housing 110. When the plurality of magnet members 150 disposed in the electronic device 100 includes a first magnet member, a second magnet member, and a third magnet member which have different magnetic properties, and the first magnet member is disposed at a position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, the electronic device may not control the second external electronic device 1333, 1337. When the second magnet member is disposed at the position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, a TV may be determined as the second external electronic device. When the third magnet member is disposed at the position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, an air conditioner may be determined as the second external electronic device.

[0236] According to one or more embodiments, the electronic device 100 may identify (detect) that the second housing 120 rotates relative to the first housing 110, and may receive input of an additional operation. Referring to FIG. 20, the electronic device 100 may detect that the position of the electronic device 100 is displaced while the electronic device 100 is worn by the user, and, when the trajectory of the detected position displacement corresponds to a set trajectory, the second external electronic device 1333, 1337 may be controlled to perform an operation corresponding to the set trajectory. For example, the electronic device 100 may identify (detect) the position displacement of the electronic device 100 and the trajectory thereof through a gyro sensor or an acceleration sensor.

[0237] For example, when the types of second external electronic devices 1333, 1337 are different, the second electronic devices 1333, 1337 may be controlled to perform different operations even if the electronic device 100 is displaced along the same trajectory. For example, the electronic device 100 may determine the TV as the second external electronic device as the second housing 120 rotates relative to the first housing 110, and, when it is identified that the position of the electronic device 100 is displaced toward the first direction, the TV may be controlled to increase the volume of the TV. For example, the electronic device 100 may determine the air conditioner as the second external electronic device as the second housing 120 rotates relative to the first housing 110, and, when it is identified that the position of the electronic device 100 is displaced toward the first direction, the air conditioner may be controlled to change the operation mode of the air conditioner.

In this case, the plurality of ring-shaped housings 110, 120 may be rotated relative to at least one other housing by the user. In this case, at least one of the plurality of ring-shaped housings 110, 120 may be rotated relative to at least one other housing under force from the user. In one or more embodiments, at least one of the plurality of ring-shaped housings 110, 120 may be rotated relative to at least one other housing by receiving a rotating force from the user. For example, while the electronic device 100 is worn by the user, at least a part of the plurality of ring-shaped housings 110, 120 included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force from the user. For example, while the electronic device 100 is worn on user's index finger, at least a part of the plurality of ring-shaped housings 110, 120 included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force by user's thumb.

The electronic device 100 according to one or more embodiments may include a magnet member 150, such that, when the plurality of ring-shaped housings 110, 120 rotate, the electronic device 100 may detect a change in the magnetic force generated by the magnet member 150 and may identify (detect) a rotation attribute of the plurality of ring-shaped housings 110, 120 based on the detected change in the magnetic force. According to one or more embodiments, the electronic device 100 may include a plurality of magnet members 150, thereby detecting a rotation of at least one of the plurality of ring-shaped housings 110, 120.

[0109] In one or more embodiments, the electronic device 100 may include a hall sensor 130. In one or more embodiments, the hall sensor 130 may include a hall element. In one or more embodiments, the hall sensor 130 may detect the existence of a magnetic field, a location of occurrence, and a strength thereof.

In one or more embodiments, when at least one of the plurality of housings rotates, the hall sensor 130 included in the electronic device 100 may detect a change in the magnetic force acting on the hall sensor 130 according to the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings. For example, when at least one of the plurality of housings rotates, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0112] According to one or more embodiments, the electronic device 100 may include a first housing 110 and a second housing 120. In one or more embodiments, the first housing 110 and the second housing 120 may be formed in the same shape or may be formed in different shapes. According to one or more embodiments, the first housing 110 and the second housing 120 may have different sizes. In one or more embodiments, the first housing 110 and the second housing 120 may be formed in ring shapes having different diameters. For example, the ring-shaped first housing 110 may have a diameter shorter than that of the ring-shaped second housing 120. For example, the ring-shaped first housing 110 may have a diameter longer than that of the ring-shaped second housing 120. For example, the electronic device 100 may include two ring-shaped housings having the second housing 120 coupled (connected) to be rotatable relative to the first housing 110. For example, the electronic device 100 may include two ring-shaped housings having the first housing 110 coupled (connected) to be rotatable relative to the second housing 120. For example, the first housing 110 and the second housing 120 may have different diameters, and the second housing 120 may be disposed on the outer side of the electronic device 100 and the first housing 110 may be disposed on the inner side of the electronic device 100. For example, the second housing 120 may have a diameter larger than that of the first housing 110, and the second housing 120 may be disposed on the outer side of the electronic device 100, and the first housing 110 may be disposed on the inner side of the electronic device 100.

[0113] According to one or more embodiments, the housings 110, 120 of the electronic device 100 may include a structure that is hollow inside. In one or more embodiments, the housings 110, 120 of the electronic device 100 may be a structure that is filled inside. According to one or more embodiments, in the electronic device 100 including the ring-shaped housings 110, 120, the housings 110, 120 may have a structure that is hollow inside. For example, in the electronic device 100 including the ring-shaped housings 110, 120, the ring-shaped housings 110, 120 may be configured to form a ring-shaped inner space that is hollow inside. However, embodiments are not limited thereto.

[0114] According to one or more embodiments, the hall sensor 130 may be disposed in the ring-shaped housings 110, 120. In the electronic device 100 according to one or more embodiments, the ring-shaped housings 110, 120 may include a ring-shaped inner space that is hollow inside, and the hall sensor 130 may be disposed in the inner space. In the electronic device 100 according to one or more embodiments, the ring-shaped housings 110, 120 may include a ring-shaped inner space that is hollow inside, and a printed circuit board (PCB) may be disposed in the inner space. In one or more embodiments, the hall sensor 130 may be disposed adjacent to the printed circuit board 250. For example, the hall sensor 130 may be disposed to be in contact with the printed circuit board 250.

[0115] According to one or more embodiments, the hall sensor 130 and the plurality of magnet members 150 may be disposed in different housings 110, 120. For example, the hall sensor 130 may be disposed in the first housing 110, and the plurality of magnet members 150 may be disposed in the second housing 120. For example, the hall sensor 130 may be disposed in the second housing 120, and the plurality of magnet members 150 may be disposed in the first housing. However, embodiments are not limited thereto.

[0116] In one or more embodiments, the plurality of magnet members 150 may be disposed at positions adjacent to the hall sensor 130. For example, when the hall sensor 130 is disposed in the first housing 110, the plurality of magnet members 150 may be disposed at positions adjacent to and facing the first housing 110 in the second housing 120. Accordingly, when the second housing 120 rotates relative to the first housing 110, the change in the magnetic force which is detected by the hall sensor 130 may be more accurately detected due to the rotation of the plurality of magnet members 150. However, the arrangement method of the plurality of magnet members 150 and the hall sensor 130 is not limited thereto.

[0117] In one or more embodiments, the hall sensor 130 and the plurality of magnet members 150 may be disposed in different housings 110, 120, and the plurality of housings 110, 120 may be disposed to be rotatable relative to at least one other housing. For example, the hall sensor 130 may be disposed in the first housing 110 and the plurality of magnet members 150 may be disposed in the second housing 120, and the first housing 110 and the second housing 120 may be disposed to be rotatable relative to each other. For example, the hall sensor 130 may be disposed in the second housing 120 and the plurality of magnet members 150 may be disposed in the first housing 110, and the first housing 110 and the second housing 120 may be disposed to be rotatable relative to each other. In this case, as at least one of the plurality of housings 110, 120 rotates relative to at least one other housing, the plurality of magnet members 150 in the housing may rotate relative to at least one other housing. For example, as the second housing 120 rotates relative to the first housing 110, the plurality of magnet members 150 in the second housing 120 may rotate relative to the first housing 110 and the hall sensor 130 in the first housing 110. In one or more embodiments, as the plurality of magnet members 150 rotate relative to at least one other housing, the gap between the hall sensor 130 and the plurality of magnet members 150 may be changed. For example, as the plurality of magnet members 150 in the second housing 120 rotate relative to the first housing 110, the gap with the hall sensor 130 in the first housing 110 may be changed. In one or more embodiments, as the gap between the hall sensor 130 and the plurality of magnet members 150 is changed, the magnetic force acting on the hall sensor 130 may be changed. In one or more embodiments, the hall sensor 130 may detect the changed magnetic force. In one or more embodiments, the hall sensor 130 may detect a change attribute in the magnetic force. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0118] The electronic device 100 according to one or more embodiments may identify (detect) an attribute of at least one of the plurality of housings 110, 120 rotating relative to at least one other housing, based on the change attribute in the magnetic force which is detected via the hall sensor 130. For example, the electronic device 100 may identify (detect) an attribute of the second housing 120 rotating relative to the first housing 110, based on the change attribute in the magnetic force which is detected via the hall sensor 130. In one or more embodiments, the operation of identifying, by the electronic device 100, a rotation attribute of at least one of the plurality of housings 110, 120 based on the change attribute in the magnetic force may be performed by a processor (for example, 210 of FIG. 2). For example, the electronic device 100 may identify (detect) a rotation attribute of the second housing 120 relative to the first housing 110, based on the change attribute in the magnetic force, through the processor (for example, 210 of FIG. 2). For example, the rotation attribute of the second housing 120 relative to the first housing 110 may include a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, or a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation. However, embodiments are not limited thereto. Details related thereto will be described with reference to FIGS. 4 to 12.

[0119] FIGS. 4A and 4B are views to explain a method by which the magnet members 150 are arranged in the electronic device, and a method of identifying a rotation attribute of a housing through a change attribute in the magnetic force caused by rotation of the housing.

[0120] In one or more embodiments, when at least one of the plurality of housings rotates, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings.

[0121] FIGS. 4A and 4B illustrate a change attribute in the magnetic force when the second housing 120 rotates in different directions relative to the first housing 110.

[0122] According to one or more embodiments, at least one magnet member of the plurality of magnet members 150 may have a different magnetic property from that of at least one other magnet member.

[0123] In one or more embodiments, the magnet members 150 having different magnetic properties may include the magnet members 150 having different magnetic forces acting on the hall sensor 130. In one or more embodiments, the magnet members 150 having different magnetic properties may include the magnet members 150 have different polarities of magnetic forces acting on the hall sensor 130. For example, referring to FIGS. 4A and 4B, the plurality of magnet members 150 may include magnet members 451, 453, 455, 457 having a first magnetic property and magnet members 452, 454, 456, 458 having a second magnetic property. For example, the magnet members 451, 453, 455, 457 having the first magnetic property may have a relatively strong magnetic property than the magnet members 452, 454, 456, 458 having the second magnetic property. For example, the magnet members 451, 453, 455, 457 having the first magnetic property may have the opposite polarity to that of the magnet members 452, 454, 456, 458 having the second magnetic property.

[0124] According to one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals.

[0125] In one or more embodiments, at least a part of the plurality of magnet members 150 may be a plurality of magnet members 150 which are arranged at different intervals. In one or more embodiments, each of the gaps between the plurality of magnet members 150 may be different. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually increase. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually decrease.

[0126] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet member sets. According to one or more embodiments, the magnet member sets may include magnet members 150 having different magnetic properties. According to one or more embodiments, the gaps between the magnet members 150 included in the same magnet member set may be shorter than the gaps between the magnet members 150 included in different magnet member sets. The electronic device 100 according to one or more embodiments may include a first magnet member set and a second magnet member set. In this case, the gap between the magnet members in the first magnet member set may be shorter than the gap between the first magnet member set and the second magnet member set.

[0127] For example, referring to FIG. 4, the plurality of magnet members 150 may include a plurality of magnet member sets including one of each of the magnet members 451, 453, 455, 457 having the first magnetic property and the magnet members 452, 454, 456, 458 having the second magnetic property. In this case, the magnet members 451, 453, 455, 457 having at least one first magnetic property, and the magnet members 452, 454, 456, 458 having at least one second magnetic property may be included in the same magnet member set. The first magnetic property and the second magnetic property may be the same as or different from each other. However, embodiments related to the plurality of magnet member sets included in the plurality of magnet members 150 are not limited thereto.

[0128] According to one or more embodiments, the electronic device 100 may control the hall sensor 130 to identify (detect) a change in the magnetic force that is generated by the plurality of magnet members 150 and is detected by the hall sensor 130 as the second housing 120 rotates relative to the first housing 110 by a user input. In one or more embodiments, the electronic device 100 may control the hall sensor 130 to identify (detect) a change in the magnetic force that is generated by the plurality of magnet members 150 and is detected by the hall sensor 130 as the first housing 110 rotates relative to the second housing 120 by a user input.

[0129] In one or more embodiments, when at least one of the plurality of housings rotates, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0130] Referring to FIG. 4A, the second housing 120 may rotate in a first direction (anti-clockwise) relative to the first housing 110. In this case, the magnet member 452 having the second magnetic property may pass through a portion adjacent to the hall sensor 130 first, and then, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 452 having the second magnetic property, first, and then, may detect the magnetic force generated by the magnet member 451 having the first magnetic property.

[0131] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a magnetic force relatively smaller than that of the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the first direction relative to the first housing 110, the magnet member 452 having the second magnetic property which generates a relatively small magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 451 having the first magnetic property which generates a relatively large magnetic force, and then, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, when the second housing 120 rotates in the first direction relative to the first housing 110, the hall sensor 130 may detect the relatively small magnetic force first, and may detect the relatively great magnetic force later.

[0132] Referring FIG. 4B, the second housing 120 may rotate in a second direction (clockwise) which is opposite to the first direction, relative to the first housing 110. In this case, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130, first, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 451 having the first magnetic property, first, and then, may detect the magnetic force generated by the magnet member 452 having the second magnetic property.

[0133] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the magnet member 451 having the first magnetic property that generates a relatively great magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 452 having the second magnetic property that generates a relatively large magnetic force, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4B, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the hall sensor 130 may detect the relatively great magnetic force, first, and may detect the relatively small magnetic force later.

[0134] According to one or more embodiments, the electronic device 100 may identify (detect) an attribute of the plurality of ring-shaped housings rotating relative to each other.

[0135] For example, the attribute of the plurality of ring shaped housings rotating relative to each other may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation. However, embodiments are not limited thereto.

[0136] Referring to FIG. 4A, the second housing 120 may rotate in the first direction relative to the first housing 110. In this case, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130 first, and then, the magnetic member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the electronic device 100 may first detect the magnetic force generated by the magnetic member 452 having the second magnetic property through the hall sensor 130, and then, may detect the magnetic force generated by the magnet member 451 having the first magnetic property and an attribute of change in the magnetic force. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, based on the characteristic of the magnet member 451 having the first magnetic property, the characteristics of the magnet member 452 having the second magnetic property, and the magnetic force detected through the hall sensor 130 and the attribute of change in the magnetic force.

[0137] For example, at a position closest to the hall sensor 130, the magnet members 150 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 150 having the first magnetic property. In this case, when the second housing 120 rotates in the first direction relative to the first housing 110, the magnet member 452 having the second magnetic property that generates a relatively small magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 451 having the first magnetic property that generates a relatively great magnetic force, and thereafter, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4A, when the second housing 120 rotates in the first direction relative to the first housing 110, the hall sensor 130 may first detect the relatively small magnetic force, and may detect the relatively large magnetic force later. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, based on the relatively small magnetic force being detected first by the hall sensor 130 and the relatively great magnetic force being detected later.

[0138] Referring to FIG. 4B, the second housing 120 may rotate in the second direction opposite to the first direction relative to the first housing 110. In this case, the magnet member 451 having the first magnetic property may pass through the portion adjacent to the hall sensor 130 first, and then, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. In this case, the hall sensor 130 may detect the magnetic force generated by the magnet member 451 having the first magnetic property first, and then, may detect the magnetic force generated by the magnet member 452 having the second magnetic property. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing is the second direction, based on the characteristic of the magnet member 451 having the first magnetic property, the characteristic of the magnet member 452 having the second magnetic property, and the magnetic force detected through the hall sensor 130 or the attribute of change in the magnetic force.

[0139] For example, at a position closest to the hall sensor 130, the magnet members 452, 454, 456, 458 having the second magnetic property may generate a relatively smaller magnetic force than the magnet members 451, 453, 455, 457 having the first magnetic property. In this case, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the magnet member 451 having the first magnetic property that generates a relatively great magnetic force may pass through the portion adjacent to the hall sensor 130 before the magnet member 452 having the second magnetic property that generates a relatively large magnetic force, and thereafter, the magnet member 452 having the second magnetic property may pass through the portion adjacent to the hall sensor 130. Accordingly, referring to FIG. 4B, when the second housing 120 rotates in the second direction which is opposite to the first direction relative to the first housing 110, the hall sensor 130 may first detect the relatively great magnetic force, and may detect the relatively small magnet force later. In this case, the electronic device 100 may identify (detect) that the direction in which the second housing 120 rotates relative to the first housing 110 is the second direction, based on the relatively great magnetic force being detected first by the hall sensor 130 and the relatively small magnetic force being detected later.

[0140] FIGS. 5A and 5B illustrate a method by which magnet members 150 are arranged in the electronic device 100, and a method of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0141] FIG. 5A illustrates an inner structure of the electronic device 100 which is rotatable in a positive direction 510 or a negative direction 520 on the x-axis. In FIG. 5A, the hall sensor 130 may be disposed in the z-axis direction or on a portion adjacent to the z-axis direction relative to the magnet members 150 with reference to a state in which the plurality of magnet members 150 are disposed closest thereto. For example, the plurality of magnet members 150 may be disposed in the second housing 120, and the hall sensor 130 may be disposed at a position adjacent to the plurality of magnet members 150 in the z-axis direction in the first housing 110.

[0142] FIG. 5B illustrates a graph showing a change attribute in the magnetic force when the second housing 120 of the electronic device 100 rotates in the positive direction 510 on the x-axis relative to the first housing 110, and a graph showing a change attribute in the magnetic force when the second housing 120 of the electronic device 100 rotates in the negative direction 520 of the x-axis relative to the first housing 110.

[0143] Referring to FIG. 5A, the plurality of magnet members 150 may include a plurality of magnet members 150 having different magnitudes of magnetic properties. The plurality of magnet members 150 may include a magnetic member set which is comprised of a plurality of magnet members 150. For example, the magnet member set may include a plurality of magnet members 150 which have different magnitudes of magnetic properties. For example, a plurality of magnet members 150 included in the same magnet member set may be disposed to be in contact with one another, or may be disposed to be spaced apart from one another. For example, the plurality of magnet members 150 included in the same magnet member set may be arranged in the second housing 120 in a direction parallel to the direction in which the second housing 120 rotates relative to the first housing 110. For example, the plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 having different magnitudes of magnetic properties. The two magnet members 150 having different magnitudes of magnetic properties may be disposed such that portions having the same polarity in the magnet members are positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. For example, the two magnet members 150 having different magnitudes of magnetic properties may be disposed such that the portions having the N-pole in the magnet members are positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130.

[0144] For example, referring to FIG. 5, the attribute of the magnetic force detected by the hall sensor 130 may be different according to the direction of rotation of the second housing 120 relative to the first housing 110. The plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 having different magnitudes of magnetic properties. In this case, the two magnet members 150 having different magnitudes of magnetic properties may be disposed such that the portion having the N-pole on each magnet member is positioned in a direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. In addition, the magnet member that has a relatively large magnitude of a magnetic property out of the two magnet members 150 of the different magnitudes of the magnetic properties may be disposed to be positioned in the positive direction on the x-axis with reference to the magnet member that has a relatively small magnitude of a magnetic property.

[0145] For example, when the second housing 120 rotates relative to the first housing 110, some of the magnet members 150 may rotate toward the positive direction 510 on the x-axis in the portion closest to the hall sensor 130. In this case, the magnet member that has the relatively large magnitude of the magnetic property may reach the position adjacent to the hall sensor before the magnet member that has the relatively small magnitude of the magnetic property. In this case, as shown in FIG. 5B, the hall sensor 130 may first detect the relatively strong magnetic force, and may detect the relatively weak magnetic force later. The electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on the relatively strong magnetic force being detected before the relatively weak magnetic force.

[0146] For example, when the second housing 120 rotates with reference to the first housing 110, some of the magnet members 150 may rotate toward the negative direction 520 on the x-axis in the portion closest to the hall sensor 130. In this case, the magnet member that has the relatively small magnitude of the magnetic property may reach the position adjacent to the hall sensor 130 before the magnet member that has the relatively large magnitude of the magnetic property. Accordingly, as shown in FIG. 5B, the hall sensor 130 may first detect the relatively weak magnetic force, and may detect the relatively strong magnetic force later. The electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on the relatively weak magnetic force being detected through the hall sensor 130 before the relatively strong magnetic force.

[0147] FIGS. 6A and 6B are views to explain an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0148] FIG. 6A may correspond to FIG. 5A, and FIG. 6B may correspond to FIG. 5B. Accordingly, redundant explanations may be omitted and the difference between the embodiment shown in FIGS. 5A and 5B and the embodiment shown in FIGS. 6A and 6B will be highlighted.

[0149] Compared to the embodiment illustrated in FIGS. 5A and 5B, the embodiment of FIGS. 6A and 6B has magnet members 150 which are included in a single magnet member set and are positioned at a relatively long distance.

[0150] In one or more embodiments, the plurality of magnet members 150 included in the single magnet member set may be disposed adjacent to one another or may be disposed at relatively long distances. As shown in FIG. 6A, the plurality of magnet members 150 may be arranged at relatively longer intervals than in the embodiment illustrated in FIG. 5A. In this case, a time period during which a relatively strong magnetic force is detected and a time period during which a relatively weak magnetic force is detected may be relatively clearly distinguished from each other. In this case, referring to the graphs of the change in the magnetic force shown in FIG. 5B and FIG. 6B, in the graph of the change in the magnetic force shown in FIG. 6B, the period during which a relatively strong magnetic force is detected and the period during which a relatively weak magnetic force is detected may be identified more clearly. Accordingly, compared to when the plurality of magnet members 150 are completely in contact with one another or are positioned at relatively short distances, when the plurality of magnet members 150 are positioned at relatively long distances, the change in the magnetic force may be more clearly identified, so that malfunction may be minimized and the accuracy of identifying the rotation attribute of the housing may be enhanced. Accordingly, the gaps between the plurality of magnet members may be set to a predetermined distance or longer in order to enhance the accuracy of identifying the rotation attribute of the housing and to reduce the probability of malfunction.

[0151] FIGS. 7A, 7B, and 7C are views to explain an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0152] Referring to FIG. 7A, the plurality of magnet members 150 may include a plurality of magnet members 150 having different polarities. In one or more embodiments, the plurality of magnet members 150 may be disposed in the second housing 12 such that portions of different polarities in the respective magnet members are adjacent to the first housing 110. For example, the plurality of magnet members 150 may include a first magnet member and a second magnet member, and may be disposed in the second housing 120, such that a portion of the first magnet member that has a first polarity and a portion of the second magnet member that has a second polarity are adjacent to the first housing 110. In this case, the portion of the first magnet member having the first polarity and the portion of the second magnet member having the second polarity may be disposed in a direction adjacent to the hall sensor 130 in the first housing 110. For example, the first polarity and the second polarity may be opposite polarities. For example, the plurality of magnet members 150 may include a first magnet member and a second magnet member, and may be disposed in the second housing 120 such that the N-pole portion of the first magnet member and the S-pole portion of the second magnet member are adjacent to the first housing 110.

[0153] Referring to FIG. 7C, the N-pole portion and the S-pole portion of one magnet member may be disposed in the second housing 120 to be adjacent to the first housing 110. In one or more embodiments, as shown in FIG. 7C, portions of the different polarities in one magnet member may be arranged on the second housing 120 along a direction in which the second housing 120 rotates relative to the first housing 110. The plurality of magnet members 150 may include a magnet member set which is comprised of a plurality of magnet members 150. For example, the magnet member set may include a plurality of magnet members 150 with different polarities. For example, the plurality of magnet members 150 included in the same magnet member set may be disposed to be in contact with one another, or may be disposed to be spaced apart from one another. For example, the plurality of magnet members 150 included in the same magnet member set may be arranged such that portions having different polarities are disposed on the second housing 120 along the direction in which the second housing 120 rotates relative to the first housing 110. For example, two magnet members 150 may be disposed such that the portions having different polarities in the respective magnet members are positioned in the direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130.

[0154] Referring to the examples of FIGS. 7A, 7B, and 7C, the attribute of the magnetic force detected by the hall sensor 130 may vary according to the direction in which the second housing 120 rotates relative to the first housing 110. In one or more embodiments, the plurality of magnet members 150 may include at least one magnet member set which is comprised of two magnet members 150 with different polarities. The two magnet members 150 with different polarities may be disposed such that the N-pole portion and the S-pole portion of the magnet members are positioned in the direction adjacent to the hall sensor 130 with reference to the state in which the magnet members 150 are positioned closest to the hall sensor 130. The magnet member having the N-pole portion that is disposed in the direction adjacent to the hall sensor 130 out of the two magnet members 150 with different polarities may be disposed to be positioned in the positive direction on the x-axis with reference to the magnet member having the S-pole portion that is disposed in the direction adjacent to the hall sensor 130.

[0155] Referring to FIGS. 7A and 7C, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the positive direction 710 on the x-axis in the portion closest to the hall sensor 130. In this case, the S-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the N-pole portion. Accordingly, referring to FIG. 7B, when the S-pole portion of a magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120 (for example, the negative direction on the z-axis in FIGS. 7A and 7C), the hall sensor 130 may detect the repulsive force first and may detect the attractive force later. The electronic device may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the repulsive force being detected before the attractive force through the hall sensor 130.

[0156] Referring to FIGS. 7A and 7B, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the negative direction 702 on the x-axis in the portion closest to the hall sensor 130. In this case, the N-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the S-pole portion of the magnet member. Accordingly, referring to FIG. 7B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120, the hall sensor 130 may detect the attractive force first and may detect the repulsive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the attractive force being detected before the repulsive force through the hall sensor 130.

[0157] FIGS. 8A and 8B illustrate an example of arrangements of magnet members 150 in the electronic device, and an example of identifying a rotation attribute of a housing through a change attribute in the magnetic force according to one or more embodiments.

[0158] In the embodiments of FIGS. 4A to 7C, the hall sensor 130 and the plurality of magnet members 150 are disposed in different housings. However, according to one or more embodiments, an arrangement direction of a magnet member in the hall sensor 130 may be changed as shown in FIGS. 8A and 8B.

[0159] Referring to FIG. 8A, the N-pole portion and the S-pole portion of the magnet member in the hall sensor 130 may be disposed along the direction in which the first housing 110 rotates relative to the second housing 120. In one or more embodiments, as shown in FIG. 8A, the portions of different polarities in one magnet member may be disposed in the hall sensor 130 along the direction in which the first housing 110 rotates relative to the second housing 120 (for example, in the +x-axis direction or-x-axis direction of FIG. 8A).

[0160] Referring to the example of FIGS. 8A and 8B, the attribute of the magnetic force detected by the hall sensor 130 may be different according to the direction in which the second housing 120 rotates relative to the first housing 110.

[0161] For example, referring to FIG. 8A, when the second housing 120 rotates relative to the first housing 110, some magnet members may rotate toward the positive direction 810 on the x-axis in the portion closest to the hall sensor 130. In this case, the S-pole portion of the magnet member in the hall sensor 130 may reach the position adjacent to the hall sensor 130 before the N-pole portion. Accordingly, referring FIG. 8B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in a direction adjacent to the second housing 120 (for example, the negative direction on the z-axis in FIG. 8A), the hall sensor 130 may detect the attractive force first, and may detect the repulsive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the repulsive force being detected before the attractive force through the hall sensor 130.

[0162] Referring to FIG. 8A, when the second housing 120 rotates relative to the first housing 110, some magnet members 150 may rotate toward the negative direction 820 on the x-axis in the portion closest to the hall sensor 130. In this case, the N-pole portion of the magnet member may reach the position adjacent to the hall sensor 130 before the S-pole portion. Accordingly, referring to FIG. 8B, when the S-pole portion of the magnet member in the hall sensor 130 is disposed in the direction adjacent to the second housing 120, the hall sensor 130 may detect the repulsive force first and may detect the attractive force later. The electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on the attractive force being detected before the repulsive force through the hall sensor 130.

[0163] FIGS. 9A and 9B illustrate example of arrangements of magnet members 150 at different intervals in the electronic device, and a change attribute in in the magnetic force according to one or more embodiments.

[0164] FIG. 9A illustrates an example of arrangements of magnet members 150 at different intervals in the electronic device 100 according to one or more embodiments, and FIG. 9B is a graph showing a change attribute in the magnetic force while the second housing 120 is rotating relative to the first housing 110 when the magnet members 150 are arranged at different intervals as shown in FIG. 9A.

[0165] According to one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals.

[0166] In one or more embodiments, at least a part of the plurality of magnet members 150 may be a plurality of magnet members 150 which are arranged at different intervals. In one or more embodiments, the gaps between the plurality of magnet members 150 may all be different. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually increase. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the gaps between the plurality of magnet members 150 gradually decrease. For example, when N magnet members 150 are arranged in the electronic device 100, the plurality of magnet members 150 may include a first magnet member, a second magnet member, . . . , an M-th magnet member, . . . , and an N-th magnet member. For example, the gap between the second magnet member and the third magnet member may be larger than the gap between the first magnet member and the second magnet member, and the gap between the M-th magnet member and the M+1-th magnet member may be larger than the gap between the M−1-th magnet member and the M-th magnet member. For example, the gap between the first magnet member and the second magnet member may have the smallest value, and the gap between the N−1-th magnet member and the N-th magnet member may have the largest value.

[0167] Referring to FIG. 9A, a plurality of magnet members (for example, 150 of FIG. 1, 910, 912, 914, 916, 918, 920 of FIG. 9A) may be arranged such that the gaps between the plurality of magnet members (for example, 150 of FIG. 1, 910, 912, 914, 916, 918, 920 of FIG. 9A) gradually increase. Referring to FIG. 9A, six magnet members 910, 912, 914, 916, 918, 920 may be arranged in the electronic device 100. The six magnet members 150 may be the first magnet member 910, the second magnet member 912, the third magnet member 914, the fourth magnet member 916, the fifth magnet member 918, and the sixth magnet member 920. For example, a gap between the first magnet member 910 and the second magnet member 912 may be a first gap, a gap between the second magnet member 912 and the third magnet member 914 may be a second gap, a gap between the third magnet member 914 and the fourth magnet member 916 may be a third gap, a gap between the fourth magnet member 916 and the fifth magnet member 918 may be a fourth gap, and a gap between the fifth magnet member 918 and the sixth magnet member 920 may be a fifth gap. In this case, for example, the second gap may have a larger value than the first gap, the third gap may have a larger value than the second gap, the fourth gap may have a larger value than the third gap, and the fifth gap may have a larger value than the fourth gap. In this case, referring to FIGS. 9A and 9B, when the second housing 120 rotates relative to the first housing 110, the plurality of magnet members 150 may rotate in a direction to cause the first magnet member 910, the second magnet member 912, the third magnet member 914, and the fourth magnet member 916 to reach the position closest to the hall sensor 130 in sequence. In this case, the time interval between the times at which the greatest magnetic force is detected may gradually increase. For example, the time interval between the time 922 at which the greatest magnetic force is detected by the second magnet member 912 at the hall sensor 130 and the time 924 at which the greatest magnetic force is detected by the third magnet member 914 at the hall sensor 130 may be longer than the time interval between the time 920 at which the greatest magnetic force is detected by the first magnet member 910 at the hall sensor 130 and the time 922 at which the greatest magnetic force is detected by the second magnet member 912 at the hall sensor 130. In one or more embodiments, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual increase in the time interval between the times 920, 922, 924 at which the greatest magnetic force is detected through the hall sensor 130.

[0168] In one or more embodiments, when the second housing 120 rotates relative to the first housing 110 in a direction opposite to the embodiment described above, the electronic device 100 may identify (detect) the direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual decrease in the time interval between the times 920, 922, 924 at which the greatest magnetic force is detected through the hall sensor 130.

[0169] In one or more embodiments, the plurality of magnet members 150 may be irregularly arranged at different intervals without a gradual increase or decrease in the gaps between the plurality of magnet members 150. In this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the gaps between the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0170] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals and have different magnetic properties. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the magnetic properties of the plurality of magnet members 15, information on the gaps between the plurality of magnet members 150, and a change attribute in the magnetic force detected through the hall sensor 130.

[0171] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet member sets each including a plurality of magnet members 150. In one or more embodiments, at least some of the plurality of magnet member sets may be a plurality of magnet member sets which are arranged at different intervals. In one or more embodiments, the gaps between the plurality of magnet member sets may all be different. In one or more embodiments, the plurality of magnet member sets may be arranged such that the gaps between the plurality of magnet member sets gradually increase. In one or more embodiments, the plurality of magnet member sets may be arranged such that the gaps between the plurality of magnet member sets gradually decrease.

[0172] FIGS. 10A and 10B illustrate examples of arrangement of magnet members 150 having different magnetic properties in the electronic device, and a change attribute in the magnetic force according to one or more embodiments.

[0173] According to one or more embodiments, at least one magnet member of the plurality of magnet members 150 may have a different magnetic property from that of at least one other magnet member. In one or more embodiments, the magnet members 150 having different magnetic properties may include the magnet members 150 having different magnetic forces acting on the hall sensor 130. For example, the magnet members having different magnetic properties may include the magnet members 150 having different polarities of magnetic forces acting on the hall sensor 130. For example, the magnet members having different magnetic properties may include the magnet members 150 having different magnitudes of magnetic forces acting on the hall sensor 130.

[0174] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged in order of decreasing the magnitude of the magnetic property. In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged in order of increasing the magnitude of the magnetic property. For example, the plurality of magnet members 150 may further include a first magnet member, a second magnet member, and a third magnet member, and the first magnet member, the second magnet member, and the third magnet member may be arranged in order of decreasing the magnitude of the magnetic property.

[0175] FIG. 10A illustrates an example of the plurality of magnet members 150 which are arranged in the electronic device 100 in order of decreasing the magnitude of the magnetic property, and FIG. 10B is a graph showing a change attribute in the magnetic force while the second housing 120 is rotating relative to the first housing 110 when the magnet members 150 are arranged in order of decreasing the magnitude of the magnetic property as shown in FIG. 10A.

[0176] In one or more embodiments, at least some of the plurality of magnet members 150 may be a plurality of magnet members 150 which have magnetic properties of different magnitudes. In one or more embodiments, the magnitudes of the magnetic properties of the plurality of magnet members 150 may all be different. In one or more embodiments, the plurality of magnet members 150 may be arranged such that the magnitude of the magnetic property of each magnet member gradually increases. In one or more embodiments, the plurality of magnet members 150 may be arranged in order of decreasing the magnitude of the magnetic property. For example, when N magnet members 150 are arranged in the electronic device 100, the plurality of magnet members 150 may include a first magnet member, a second magnet member, . . . , an M-th magnet member, . . . , and an N-th magnet member. For example, the magnitude of the magnetic property of the second magnet member may be greater than the magnitude of the magnetic property of the first magnet member, and the magnitude of the magnetic property of the M-th magnet member may be greater than the magnitude of the magnetic property of the M−1-th magnet member. For example, the magnitude of the magnetic property of the first magnet member may have a smallest value out of the N magnet members 150, and the magnitude of the magnetic property of the N-th magnet member may have a greatest value.

[0177] Referring to FIG. 10A, a plurality of magnet members (for example, 150 of FIG. 1, 1010, 1012, 1014, 1016, 1018, 1020, 1022, 1024 of FIG. 10A) may be arranged in order of decreasing the magnitude of the magnetic property. Referring to FIG. 10A, 8 magnet members (for example, 150 of FIG. 1, 1010, 1012, 1014, 1016, 1018, 1020, 1022, 1024 of FIG. 10A) may be disposed in the electronic device 100, and the 8 magnet members 150 may be a first magnet member 1010, a second magnet member 1012, a third magnet member 1014, a fourth magnet member 1016, a fifth magnet member 1018, a sixth magnet member 1020, a seventh magnet member 1022, and an eighth magnet member 1024. In this case, the magnitude of the magnetic property of the second magnet member may have a greater value than the magnitude of the magnetic property of the first magnet member, the magnitude of the magnetic property of the third magnet member may have a greater value than the magnitude of the magnetic property of the second magnet member, and the magnitude of the magnetic property of the fourth magnet member may have a greater value than the magnitude of the magnetic property of the third magnet member. In this case, referring to FIGS. 10A and 10B, when the second housing 120 rotates relative to the first housing 110, the plurality of magnet members 150 may rotate in such a direction that the first magnet member 1010, the second magnet member 1012, the third magnet member 1014, and the fourth magnet member 1016 reach the position closest to the hall sensor 130 in sequence. In this case, the maximum value 1030, 1032, 1034 of the magnetic force detected may gradually decrease with time. For example, the maximum value of the magnetic force detected at the time 1032 at which the greatest magnetic force is detected by the second magnet member 1012 at the hall sensor 130 may be greater than the maximum value of the magnetic force detected at the time 1030 at which the greatest magnetic force is detected by the first magnet member 1010 at the hall sensor 130. In one or more embodiments, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual increase in the time interval between the times 1030, 1032, 1034 at which the greatest magnetic force is detected through the hall sensor 130.

[0178] In one or more embodiments, when the second housing 120 rotates relative to the first housing 110 in a direction opposite to the embodiment described above, the electronic device 100 may identify (detect) a direction in which the second housing 120 rotates relative to the first housing 110, based on a gradual decrease in the maximum value of the magnetic force at the time when the greatest magnetic force is detected through the hall sensor 130.

[0179] In one or more embodiments, the plurality of magnet members 150 may be irregularly arranged regardless of the magnitude of the magnetic property without a gradual increase or decrease in the magnitude of the magnetic property of the plurality of magnet members 150. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 to the first housing 110, based on information on the magnetic property of the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0180] In one or more embodiments, the plurality of magnet members 150 may include a plurality of magnet members 150 which are arranged at different intervals and have different magnetic properties. Even in this case, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110, based on information on the magnetic property of the plurality of magnetic members 150, information on the gaps between the plurality of magnet members 150 and a change attribute in the magnetic force detected through the hall sensor 130.

[0181] FIGS. 11A and 11B illustrate a change attribute in the magnetic force according to a rotation speed of a housing in the electronic device according to one or more embodiments.

[0182] FIGS. 11A and 11B are views for comparing the periods of change in the magnetic force when the speed at which the second housing 120 rotates relative to the first housing 110 is different in the electronic device 100 of the same configuration. For example, FIG. 11A illustrates a case where the second housing 120 rotates relative to the first housing 110 at a relatively fast speed, and FIG. 11B illustrates a case where the second housing 120 rotates relative to the first housing 110 at a relatively slow speed.

[0183] According to one or more embodiments, in the electronic device 100 of the same configuration, when the second housing 120 rotates relative to the first housing 110 at a relatively fast speed (FIG. 11A), the period in which the plurality of magnet members 150 reach the position closest to the hall sensor 130 may be shorter than when the second housing 120 rotates relative to the first housing 110 at a relatively slow speed (FIG. 11B). Accordingly, when the second housing 120 rotates relative to the first housing 110 at the relatively fast speed (FIG. 11A), the period in which the magnetic force sensed by the hall sensor 130 has a maximum value may be shorter than when the second housing 120 rotates relative to the first housing 110 at the relatively slow speed (FIG. 11B). For example, when the second housing 120 rotates relative to the first housing 110 at the relatively fast speed (FIG. 11A), the period of change in the magnetic force sensed by the hall sensor 130 may be shorter than when the second housing 120 rotates relative to the first housing 110 at the relatively slow speed (FIG. 11B).

[0184] According to one or more embodiments, the electronic device 100 may identify (detect) a speed at which the second housing 120 rotates relative to the first housing 110, based on the period of change in magnetic force detected by the hall sensor 130. For example, the electronic device 100 may identify (detect) that the speed at which the second housing 120 rotates relative to the first housing 110 is relatively high when the period of change in the magnetic force detected via the hall sensor 130 is relatively short. For example, the electronic device 100 may identify (detect) that the speed at which the second housing 120 rotates relative to the first housing 110 is relatively low when the period of change in the magnetic force detected via the hall sensor 130 is relatively long.

[0185] According to one or more embodiments, the method by which the magnet members 150 are arranged may include a number of different methods, and is not limited to the above-described embodiments.

[0186] FIG. 12 is a flowchart of a process of identifying an attribute of rotation of the second housing 120 relative to the first housing 110 in the electronic device according to one or more embodiments.

[0187] At step 1210, the second housing 120 may rotate relative to the first housing 110.

[0188] According to one or more embodiments, the electronic device 100 may include ring-shaped housings. The electronic device 100 according to one or more embodiments may be worn on a user by the ring-shaped housings. According to one or more embodiments, the electronic device 100 may include a plurality of ring-shaped housings, and may be worn on a user by the plurality of ring-shaped housings. The plurality of ring-shaped housings may be coupled (connected) to be rotatable relative to at least one other housing. At least one of the plurality of ring-shaped housings may be rotated relative to at least one other housing under force from the user. In one or more embodiments, at least one of the plurality of ring-shaped housings may be rotated relative to at least one other housing by receiving a rotating force from the user. For example, while the electronic device 100 is worn by the user, at least a part of the plurality of ring-shaped housings included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force from the user. For example, while the electronic device 100 is worn on user's index finger, at least a part of the plurality of ring-shaped housings included in the electronic device 100 may be rotated relative to at least one other housing by receiving a force by user's thumb.

[0189] At step 1220, the magnetic force generated between the plurality of magnet members 150 and the hall sensor 130 may change. In one or more embodiments, as the second housing 120 rotates relative to the first housing 110, the magnetic force generated between the plurality of magnet members 150 and the hall sensor 130 may change. For example, when the magnet member reaches a portion closest to the hall sensor 130 due to the rotation of the housing, the magnetic force detected by the hall sensor 103 may have a maximum value or a minimum value. For example, as the gap between the magnet member and the hall sensor 130 changes due to the rotation of the housing, the magnetic force detected by the hall sensor 130 may change. For example, as the distance between the magnet member and the hall sensor 130 continuously changes due to the rotation of the housing, the magnetic force detected by the hall sensor 130 may continuously change.

[0190] At step 1230, the electronic device 100 may detect the change in the magnetic force through the hall sensor 130. In one or more embodiments, the hall sensor may detect the existence of a magnetic field, a location of occurrence, and a strength thereof. In one or more embodiments, the hall sensor 130 and the plurality of magnet members 150 may be disposed in different housings. In one or more embodiments, the hall sensor 130 included in the electronic device 100 may detect a change in the magnetic force acting on the hall sensor 130 according to the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings when at least one of the plurality of housings rotates. For example, the hall sensor 130 included in the electronic device 100 may detect a change attribute in the magnetic force acting on the hall sensor 130 by the rotation of the plurality of magnet members 150 included in at least one of the plurality of housings when at least one of the plurality of housings rotates. For example, the electronic device 100 may include a first housing 110 and a second housing 120, and, when the second housing 120 rotates relatives to the first housing 110, the hall sensor 130 included in the first housing 110 may detect a change in the magnetic force acting on the hall sensor 130 and an attribute thereof by the rotation of the plurality of magnet members 150 included in the second housing 120.

[0191] At step 1240, the electronic device 100 may identify (detect) the change attribute in the magnetic force detected. For example, the change attribute in the magnetic force may include at least one of a speed of change in the magnetic force, whether the polarity of the magnetic force is changed, an amount of change in the magnetic force, an acceleration of change in the magnetic force, a magnitude of the magnetic force before change of the magnetic force, a magnitude of the magnetic force after change of the magnetic force, a pattern of change in the magnetic force or a graph of change in the magnetic force.

[0192] At step 1250, the electronic device 100 may identify (detect) an attribute of rotation of the second housing 120 relative to the first housing 110. According to one or more embodiments, the electronic device 100 may identify (detect) the attribute of rotation of the second housing 120 relative to the first housing 110, based on the change attribute in the magnetic force detected. The attribute of the plurality of ring-shaped housings rotating relative to one another may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation. However, embodiments are not limited thereto.

[0193] FIG. 13 illustrates the electronic device 100 and peripheral devices of the electronic device 100 according to one or more embodiments.

[0194] In one or more embodiments, there may exist the electronic device 100, a first external electronic device 1310, a gateway 1320, and at least one second external electronic devices 1333, 1337.

[0195] The electronic device 100 may communicate with the first external electronic device 1310 via an antenna (for example, 280 of FIG. 2). For example, the first external electronic device 1310 may be a smartphone.

[0196] In one or more embodiments, the first external electronic device 1310 may communicate with the gateway 1320. For example, the gateway 1320 and the first external electronic device 1310 may communicate by using Wi-Fi.

[0197] In one or more embodiments, the gateway 1320 may communicate with at least one second external electronic device 1333, 1337. The second external electronic device 1333, 1337 may be, for example, a home appliance (for example, an air conditioner, a television (TV), a refrigerator). For example, the gateway 1320 may transmit a signal to control the second external electronic device 1333, 1337 to the second external electronic device 1333, 1337.

[0198] FIG. 14 is a flowchart illustrating a process of the second external electronic device performing an operation corresponding to an identified rotation attribute according to the identified rotation attribute of the electronic device in the electronic device according to one or more embodiments.

[0199] At step 1410, the electronic device 100 may transmit a signal corresponding to an identified rotation attribute to the first external electronic device 1310. In one or more embodiments, the electronic device 100 may transmit six-axis information to the first external electronic device 1310 through Bluetooth communication. For example, the attribute of the plurality of ring-shaped housings rotating relative to one another may include information on a speed at which the second housing 120 rotates relative to the first housing 110, a direction in which the second housing 120 rotates relative to the first housing 110, a position of the hall sensor 130 relative to the first housing 110 that is displaced in response to the rotation, a relative position of the second housing 120 to the first housing 110 before rotation, or a relative position of the second housing 120 to the first housing 110 after rotation.

[0200] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device 1333, 1337 may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher.

[0201] For example, the identified rotation attribute may include information indicating that the direction in which the second housing 120 rotates relative to the first housing 110 is the first direction, and the second external electronic device 1333, 1337 may be a device that performs a temperature control function. In this case, the electronic device 100 may transmit a signal to increase a target temperature of the second external electronic device 1333, 1337 to the first external electronic device 1310. For example, the identified rotation attribute may include information indicating that the rotation direction is the second direction opposite to the first direction, and the second external electronic device 1333, 1337 may be a device that performs a temperature control function. In this case, the electronic device 100 may transmit a signal to reduce the target temperature of the second external electronic device 1333, 1337 to the first external electronic device.

[0202] At step 1420, the first external electronic device 1310 may discover the second external electronic device 1333, 1337. According to one or more embodiments, the first external electronic device 1310 may receive six-axis information from the electronic device 100, and may transmit a signal related to the received information to the second external electronic device 1333, 1337. According to one or more embodiments, the first external electronic device 1310 may discover the second external electronic device 1333, 1337 existing in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and position information received from the second external electronic device 1333, 1337. In one or more embodiments, the second external electronic device 1333, 1337, which is intended to receive a signal from the first external electronic device 1310, may be discovered through antennas of the electronic device 100 and the second external electronic device 1333, 1337. The process of discovering the second external electronic device 1333, 1337 by the first external electronic device 1310 will be described in detail with reference to FIGS. 15 to 19.

[0203] At step 1430, the first external electronic device 1310 may transmit a signal to perform an operation corresponding to the identified rotation attribute to the second external electronic device 1333, 1337.

[0204] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher. The first external electronic device which receives the signal may discover the second external electronic device 1333, 1337 which exists in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and location information received from the second external electronic device 1333, 1337. The first external electronic device 1310 may transmit the signal that causes the second external electronic device 1333, 1337 identified by discovering to increase the reproduction speed of the content by a predetermined value or higher to the second external electronic device 1333, 1337.

[0205] At step 1440, the second external electronic device 1333, 1337 may perform the operation corresponding to the identified rotation attribute.

[0206] For example, the identified rotation attribute may include information indicating that the speed at which the second housing 120 rotates relative to the first housing 110 is greater than a predetermined value, and the second external electronic device may be reproducing a content such as a video or music. In this case, the electronic device 100 may transmit, to the first external electronic device 1310, a signal for increasing the reproduction speed of the content being reproduced by the second external electronic device by a predetermined value or higher. The first external electronic device which receives the signal may discover the second external electronic device 1333, 1337 which exists in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information received from the electronic device 100 and location information received from the second external electronic device 1333, 1337. The first external electronic device 1310 may transmit the signal that causes the second external electronic device 1333, 1337 identified by discovering to increase the reproduction speed of the content by a predetermined value or higher to the second external electronic device 1333, 1337. The second external electronic device 1333, 1337 which receives the signal may control an audio to increase the reproduction speed of the reproduced content by a predetermined value or higher.

[0207] FIG. 15 is a flowchart of a process of communicating with the second external electronic device through the first external electronic device by the electronic device according to one or more embodiments.

[0208] The second external electronic device 1330 of FIG. 15 may correspond to the second external electronic device 1333, 1337 of FIGS. 13, 17, and 18.

[0209] According to one or more embodiments, when the electronic device 100 detects that the electronic device is disconnected from a charger after being connected to the charger (1501), the electronic device may execute a mode for communicating with external electronic devices. For example, the electronic device 100 may execute a BLE connection mode (1502). When the electronic device 100 identifies the first external electronic device 1310, a Bluetooth Low Energy (BLE) connection may be performed between the first external electronic device 1310 and the electronic device 100 (1509). For example, the electronic device 100 and the first external electronic device 1310 may be already paired with each other or may be initially connected with each other.

[0210] According to one or more embodiments, the electronic device 100 may detect that the electronic device 100 is worn on user's body through a sensor module (1503). For example, the electronic device 100 may acquire biometric recognition information of the user through the sensor module (1504). For example, the recognized biometric recognition information may be used for identifying the user (1505). For example, the electronic device 100 may store a setting value related to at least one user in a memory (for example, a memory 220 of FIG. 2). In this case, the electronic device 100 may identify (detect) the user by comparing the recognized biometric recognition information and the stored setting value (1505). For example, the electronic device 100 may determine whether to give an authority to control the second external electronic device 1330 to the identified user according to the identified user. For example, the electronic device 100 may determine the second external electronic device 1330 to control according to the identified user. For example, when the identified user is a first user and a setting value corresponding to the first user is related to TV control, the electronic device 100 may determine the second external electronic device 1333, 1337 to identify (detect) as a television (TV).

[0211] In one or more embodiments, the electronic device 100 may transmit six-axis information of the electronic device 100 which is acquired through the sensor module to the first external electronic device 1310 (1506). A six-axis sensor may include a gyro sensor or an acceleration sensor, and may acquire the 6-axis information. The first external electronic device 1310 which receives the six-axis information from the electronic device 100 (1511) may transmit the six-axis information to the second external electronic device 1330 through the gateway 1320 (1513). The second external electronic device 1330 may receive the six-axis information of the electronic device 100 (1516), and may identify (detect) whether the second external electronic device 1330 is positioned in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the received 6-axis information of the electronic device 100 and the location information of the second external electronic device (1517). For example, the second external electronic device 1330 may identify (detect) whether the second external electronic device 1330 is positioned in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the relative positions among the first external electronic device 1310, the second external electronic device 1330 and the electronic device 100, and the 6-axis information of the electronic device 100 (1517).

[0212] In one or more embodiments, when it is identified that the second external electronic device 1330 is positioned in the direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, the second external electronic device 1330 may execute a mode to be controlled by the electronic device 100 (1518), and the electronic device 100 may execute a mode for controlling the second external electronic device 1330 (1507). When it is detected that the second housing 120 of the electronic device 100 rotates relative to the first housing 110 in the state in which the mode is executed in each of the electronic device 100 and the second external electronic device 1330 (1508), a related signal may be transmitted to the second external electronic device 1330 through the first external electronic device 1310 and the gateway 1320. The second external electronic device 1330 which receives the signal may perform an operation corresponding to the attribute of rotation of the second housing 120 of the electronic device 100 relative to the first housing 110 (1519).

[0213] FIGS. 16A, 16B, and 16C are views to explain a method by which the electronic device identifies positions of external electronic devices through an antenna 280 according to one or more embodiments.

[0214] FIG. 16A illustrates one or more embodiments in which an antenna 280 is disposed in the electronic device 100. In one or more embodiments, the antenna 280 may be disposed in the housing 110, 120 of the electronic device 100. In one or more embodiments, the antenna 280 may be a part of the housings 110, 120 of the electronic device 100. For example, the antenna 280 may be at least a part of the metal segment portion of the first housing 110 or the second housing 120. For example, the antenna 280 may include a monopole antenna or a dipole antenna.

[0215] FIG. 16B illustrates a method by which the antenna 280 is disposed in the first external electronic device 1310, the second external electronic device 1330, 1333, 1337, and the gateway 1320. In one or more embodiments, the antenna 280 may be an antenna array in which a plurality of antennas are connected. For example, the antenna 280 may be an antenna array that is arranged in the horizontal or vertical direction. Referring to FIG. 16B, a first patch antenna, a second patch antenna, and a third patch antenna may be disposed and operate in one device.

[0216] FIG. 16C illustrates a method of identifying a position of the first external electronic device 1310 or the second external electronic device 1330, 1333, 1337 through the antenna 280. For example, the antenna 280 may be an antenna that operates in an angle of departure (AoD) method or an angle of arrival (AoA) method. For example, the plurality of antennas included in the antenna array may determine a phase difference of signals by the following Equation 1:Phase⁢ Difference=d⁢ sin⁢ θ×2⁢πλEquation⁢ 1

[0217] For example, the plurality of antennas may identify (detect) relative positions of the electronic device 100 and the second external electronic device 1333, 1337, based on the phase difference between signals, which is determined by Equation 1 above.

[0218] FIG. 17 illustrates a connection structure between the electronic device and external electronic devices, and a position identification method according to one or more embodiments.

[0219] In one or more embodiments, there may exist an electronic device 100, a first external electronic device 1310, a gateway 1320, and at least one second external electronic device 1333, 1337. According to one or more embodiments, the electronic device 100 may include a BLE module (for example, a communication module 230 of FIG. 2) for Bluetooth communication, a six-axis sensor (for example, a gyro sensor, an acceleration sensor), an antenna (for example, an antenna 280 of FIG. 2), or a processor (for example, a processor 210 of FIG. 2).

[0220] The first external electronic device 1310 may include a processor and may include a communication module for Wi-Fi and Bluetooth communication.

[0221] The second external electronic device 1333, 1337 may include a processor, and may include a plurality of antenna arrays for performing BLE communication.

[0222] In one or more embodiments, a BLE connection may be performed between the first externa electronic device 1310 and the electronic device 100 (1509). For example, the electronic device 100 and the first external electronic device 1310 may be already paired with each other, or may be initially connected with each other.

[0223] In one or more embodiments, the electronic device 100 may transmit six-axis information of the electronic device 100 acquired through a sensor module to the first external electronic device 1310. The six-axis sensor may include a gyro sensor or an acceleration sensor and may acquire six-axis information. The first external electronic device 1310 which receives the six-axis information from the electronic device 100 may transmit the six-axis information to the second external electronic device 1333, 1337 through the gateway 1320.

[0224] For example, the antennas of the second external electronic device 1333, 1337 and the electronic device 100 may operate in the AoD method to cause the second external electronic device 1333, 1337 to acquire the six-axis information of the electronic device 100.

[0225] The second external electronic device 1333, 1337 may receive the six-axis information of the electronic device 100, and may identify (detect) whether the second external electronic device 1333, 1337 is positioned in a direction that the rotation axis of the plurality of housings 110, 120 of the electronic device 100 faces, based on the six-axis information of the electronic device 100 received, and position information of the second external electronic device 1333, 1337.

[0226] FIG. 18 illustrates a method of identifying positions of the electronic device and external electronic devices according to one or more embodiments.

[0227] According to one or more embodiments, the electronic device 100, the first external electronic device 1310 or the second external electronic device 1333, 1337 may include an antenna array that performs short-range wireless communication. For example, the electronic device 100, the first external electronic device 1310, or the second external electronic device 1333, 1337 may perform wireless communication by using ultra-wide band (UWB) wireless communication. In this case, each of the devices may use a wide frequency domain within a low-frequency domain, so that each of the devices may perform wireless communication without mutual interference with an existing communication system even with low spectrum power.

[0228] In one or more embodiments, the relative positions of the electronic device 100 and the second external electronic device 1333, 1337 may be identified by using the antennas of the electronic device 100 and the second external electronic device 1333, 1337.

[0229] In one or more embodiments, there may be a plurality of second external electronic devices 1333, 1337. In this case, the relative positions of the electronic device 100 and the second external electronic devices 1333, 1337 may be identified by using trilateration between the first external electronic device 1310 and the plurality of second external electronic devices 1333, 1337 or the plurality of second external electronic devices 1333, 1337.

[0230] FIGS. 19A and 19B illustrate a range in which the electronic device identifies whether an external electronic device is positioned in a direction that a rotation surface of a housing faces according to one or more embodiments.

[0231] FIGS. 19A and 19B are views to explain a method of setting a reference range for identifying whether the second electronic device 1333, 1337 is positioned in a direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces when a distance between the electronic device 100 and the second external electronic device 1333, 1337 is relatively long and when the distance is relatively short.

[0232] According to one or more embodiments, the second external electronic device 1333, 1337 being positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may include the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces facing at least a part of the outer side of the second electronic device 1333, 1337.

[0233] Referring to FIGS. 19A and 19B, the electronic device 100 may be positioned at different positions (for example, position 1, position 2), and the electronic device 100 may form an azimuth of the same degree (90°-θ) with reference to the second external electronic device 1333, 1337. Even if the electronic device 100 is positioned at a position forming the azimuth of the same degree with reference to the second external electronic device 1333, 1337, when the distance (for example, d1, d2) between the electronic device 100 and the second external electronic device 1333, 1337 is different, the angle range (for example, α1, β1) in which it is identified that the second external electronic device 1333, 1337 is positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may be different. For example, when the distance d2 between the electronic device 100 and the second external electronic device 1333, 1337 is relatively long (for example, when the electronic device 100 is positioned at position 2), the angle range (β1) in which it is identified that the second external electronic device 1333, 1337 is positioned in the direction that the rotation axis of the housings 110, 120 of the electronic device 100 faces may be narrower than when the distance (d1) between the electronic device 100 and the second external electronic device 1333, 1337 is relatively short (for example, when the electronic device 100 is positioned at position 1) (β1<α1).

[0234] FIG. 20 illustrates an example of controlling an external electronic device that is positioned in a direction that a rotation surface of a housing of the electronic device faces according to one or more embodiments.

[0235] Referring to FIG. 20, the electronic device 100 may change the second external electronic device 1333, 1337 to be controlled, or may not control the second external electronic device 1333, 1337 according to a position of the second housing 120 relative to the hall sensor 130 that is displaced in response to the rotation of the second housing 120 relative to the first housing 110. When the plurality of magnet members 150 disposed in the electronic device 100 includes a first magnet member, a second magnet member, and a third magnet member which have different magnetic properties, and the first magnet member is disposed at a position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, the electronic device may not control the second external electronic device 1333, 1337. When the second magnet member is disposed at the position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, a TV may be determined as the second external electronic device. When the third magnet member is disposed at the position closest to the hall sensor 130 in response to the rotation of the second housing 120 relative to the first housing 110, an air conditioner may be determined as the second external electronic device.

[0236] According to one or more embodiments, the electronic device 100 may identify (detect) that the second housing 120 rotates relative to the first housing 110, and may receive input of an additional operation. Referring to FIG. 20, the electronic device 100 may detect that the position of the electronic device 100 is displaced while the electronic device 100 is worn by the user, and, when the trajectory of the detected position displacement corresponds to a set trajectory, the second external electronic device 1333, 1337 may be controlled to perform an operation corresponding to the set trajectory. For example, the electronic device 100 may identify (detect) the position displacement of the electronic device 100 and the trajectory thereof through a gyro sensor or an acceleration sensor.

[0237] For example, when the types of second external electronic devices 1333, 1337 are different, the second electronic devices 1333, 1337 may be controlled to perform different operations even if the electronic device 100 is displaced along the same trajectory. For example, the electronic device 100 may determine the TV as the second external electronic device as the second housing 120 rotates relative to the first housing 110, and, when it is identified that the position of the electronic device 100 is displaced toward the first direction, the TV may be controlled to increase the volume of the TV. For example, the electronic device 100 may determine the air conditioner as the second external electronic device as the second housing 120 rotates relative to the first housing 110, and, when it is identified that the position of the electronic device 100 is displaced toward the first direction, the air conditioner may be controlled to change the operation mode of the air conditioner. However, types of additional operations are not limited thereto.

[0238] As described above, an electronic device according to one or more embodiments may include a first housing 110 having a ring shape. The electronic device may include a second housing 120 having a ring shape. The first housing and the second housing may be coupled (connected) to be rotatable relative to each other. The electronic device may further include a plurality of magnet members 150. At least some of the plurality of magnet members 150 may be arranged at different intervals in the second housing 120. The electronic device may include a hall sensor 130 disposed in the first housing 110 to detect a magnetic force generated from the plurality of magnet members 150. The electronic device may include at least one processor (for example, a processor 210 of FIG. 2). The electronic device may include a memory (for example, a memory 220 of FIG. 2) configured to store instructions.
